Contactor-fuse combination 3TL62 / 63 / 66
The contactor-fuse combinations 3TL62/63/66 are type-tested units of the successful 3TL6 contactors and HV HRC fuses.A fuse holder for two fuses per phase and a control transformer for power supply have been integrated. This enables frequent switching of high normal currents in a compact space.
Contactor-fuse combination 3TL62/63/66– The Complete
The arrangement of the components on the base plateprovides optimum ventilation and thus, a high normal cur-rent, supported by the especially developed fuse holder which ensures a uniform distribution of the current. Even high requirements regarding the dielectric strength – as requested in countries like China – are fulfi lled with this design.
Due to their high reliability, the contactor-fuse combina-tions 3TL6 are used where frequent and safe switching is required, no matter whether it is for three-phase motors, transformers, reactors, capacitors or resistive consumers. With up to one million operating cycles, the contactor-fuse combinations ensure optimum availability. Their ad-vantage: High safety and reliability due to maintenance-free systems.
The contactor-fuse combinations 3TL6 are suitable for appli-cation on withdrawable parts and fi xed-mounted assemblies.Bushings and various widths across fl ats are available for easy integration.
There are many different versions of contactor-fuse combina-tions available, e.g. for one or two fuses per phase, with or without control transformer.

Contactor-Fuse Combination 3TL62 / 63 / 66

Construction
The contactor-fuse combination consists of the following components: vacuum contactor (1), insulating cover with fuse holder (2), fuse-links (3), isolating contacts (4), and an optional control transformer (5). These components are accommodated on a base plate (6).
The vacuum contactor (1) breaks the relevant currents during normal operation. To do this, the vacuum switch-ing technology, proven for more than 30 years, serves as arc-quenching principle by using vacuum interrupters. The vacuum interrupters (8) are operated by the magnet system (10) through an integral rocker (9). All components required for switching, such as the operating mechanism and closing latch (11) are accommodated in the operating mechanism box (12) and are fed with low voltage. This low voltage is either supplied separately or taken directly from the medium-voltage system through the optional control transformer (5).
The insulating cover with fuse holder (2) is mounted on one side of the contactor (1). On the other side it is raised to the necessary height by the cross-member (7). The fuse holders, which are especially conceived for the use of up to two plug-in HV HRC fuse-links, ensure a uniform distribution of the current to the two fuse-links of one phase.
The fuse-links (3) from different manufacturers can be used. Here, a maximum let-through current of 50 kA must be ob-served in order not to damage the contactor. To select the correct fuse-link, please observe the indications given in the chapter “Equipment Selection” (see page 16).
The isolating contacts (4) enable the connection to the medium-voltage system. For fi xed mounting there are fl at contacts available, and plug-in contacts for integration in withdrawable systems. With this type, the ring spring contact version offers an especially large contact surface and opti-mum power connection. The circumferential ring spring ex-pands when the fi xed contact is pushed in, providing a large contact surface. To insulate the contact arms, a plastic insu-lating sleeve is used, which can be adjusted to the different lengths of the contact system. A width across fl ats of 205, 275 or 310 mm is reached by different adjustments to the cross-members or the insulating covers with fuse holders.
The optional control transformer (5) is connected to the high-voltage terminals of the contactor-fuse combination on its primary part, so that no additional cables are required. To protect the transformer, an separate upstream fuse is series-connected on the primary side and accommodated in the cross-member. Due to its different versions, the control transformer can be optimally adjusted to the existing power system.
The front cover (13) closes the insulating cover with fuse holder with an indication opening, and offers a possibility for handling.

Mode of operation
Basically, there are three different modes or states of opera-tion: Normal operation, short circuit and overload.
During normal operation, the combination behaves like a contactor. The atmospheric pressure exerts a force on the metal bellows of the vacuum interrupter. Without the in-fl uence of the operating mechanism, this would close the contact gap.
The opening springs (1) keep the moving interrupter con-tact in open position via the integral rocker (2). To close the vacuum contactor, the compressive force of the opening springs (1) is overcome by the magnet system (3). The DC magnet system operates as an economy circuit, providing a high mechanical endurance and a low pickup and holding power. The magnet armature (4) is attracted, thus moving the integral rocker (2), which releases the moving interrupter contact from the open position. The atmospheric pressure closes the contacts. The integral rocker (2) compresses the contact pressure springs (5), thus generating the necessary contact force. When the magnetic excitation is de-energized, the opening springs (1) open the contact gap via the integral rocker (2) and the moving interrupter contact.
When a mechanical closing latch is used, the adjustment is maintained through a latch lever even if the magnet coil is not excited. The vacuum contactor is released electrically by means of a latch release coil, or mechanically by means of a latch release device.
In case of overload, a high continuous current overloads the fuse-link thermally, thus tripping the thermal striker (11). The contactor already operates within the arcing time of the fuse. The take-over current must not exceed 5 kA, as this could damage the vacuum interrupter! This is prevented by selecting the correct fuse.
In case of short circuit, the main fuse-elements (10) of the HV HRC fuse melt and evaporate at all bottlenecks already during the current rise. Arcs burn at these bottlenecks, which are cooled so effectively by the arc-quenching medium that their total arc voltage is higher than the operating voltage. This results in a rapid decrease of the current, which is inter-rupted while it is still rising. When the main fuse-elements (10) melt, the secondary fuse-element (8) evaporates as well and releases the thermal striker (11), which operates the vacuum contactor with the help of the auxiliary switch and activates the fuse trip indicator. In the optimum time sequence, the fuse has already interrupted the short-circuit current at this time.

Example: Single-line diagram for direct control of consumers
Replacement of HV HRC fuses
The fault currents stress the fuses in the phases differently, but all fuses are stressed. To obtain identical switching and safety conditions for further application again, all fuse-links should be replaced as recommended in the standards.
We advise to use our Siemens 3GD2 HV HRC fuse-link for our contactor-fuse combination. For more Information see Catalog HG 12.31, Order No. E50001-K1512-A311-A2-7600 (available as of 2011).
Short-circuit protection of HV HRC fuses
At high short-circuit currents, HV HRC fuses have a current-limiting effect, i.e. the fuse limits the short-circuit current to the let-through current. To select the fuses, the type of con-sumer must be observed, e.g. motor, transformer, capacitors.
An example for the coordination of contactor and HV HRC fuses is given in the chapter “Equipment Selection”.
Application examples
Contactor-fuse combinations are suitable for operational switching of alternating-current consumers in indoor switch-gear, and can be used e.g. for the following switching duties:
Starting of motors• Plugging or reversing the direction of rotation of motors• Switching of transformers• Switching of reactors• Switching of resistive consumers (e.g. electrical furnaces)• Switching of capacitors• Switching of compressors.•
With these duties, contactor-fuse combinations are used in conveyor and elevator systems, pumping stations, air con-ditioning systems as well as in systems for reactive power compensation, and can therefore be found in almost every industrial sector.
Utilization categories
In IEC 60470, medium-voltage power contactors are divided into different utilization categories. According to these categories, contactor-fuse combinations 3TL62/63/66 are dimensioned for different electrical consumers and operating conditions. The opposite table shows typical applications in accordance with the respective utilization categories.
DescriptionConstruction and mode of operation
1) Plugging is understood as stopping or reversing the motor rapidly by reversing motor primary connections while the motor is running
2) Inching is understood as energizing a motor once or repeatedly for short periods to obtain small movements of the driven mechanism
Utilization category Typical applications
AC-1 Non inductive or slightly inductive loads, resistance furnaces
AC-2 Slip-ring motors: Starting, switching off
AC-3 Squirrel-cage motors: Starting, switching off during running
AC-4 Squirrel-cage motors:Starting, plugging 1), reversing 1), inching 2)

Switching of motors
Contactor-fuse combinations 3TL62/63/66 are especially suit-able for frequent operation of motors in utilization category AC-3 and AC-4.
As the chopping currents of the contactors are ≤ 5 A, no unpermissibly high overvoltages are produced when started motors are switched during normal operation. However, when high-voltage motors with starting currents of ≤ 600 Aare stopped during start-up, switching overvoltages may arise. The magnitude of these overvoltages can be reduced to harmless values by means of special surge limiters.
Switching of transformers
When inductive currents are interrupted, current chopping can produce overvoltages at the contact gap. Such overvolt-ages can be controlled with a protective circuit composed of 3EF surge limiters.
Switching of capacitors
Contactor-fuse combinations can interrupt capacitive cur-rents up to 250 A up to the rated voltage of 12 kV without restrikes, and thus without overvoltages.
Surge protection via limiters
Overvoltages can arise as a consequence of multiple re-strikes or by virtual current chopping, e.g. when motors are switched in braked condition or during start-up. Motors with a starting current ≤ 600 A are endangered. Safe protection against overvoltages is ensured by surge limiters; circuit ex-amples are shown on the left.
3EF surge limiters can be arranged in parallel to the cable sealing ends, preferably in the cable compartment. The surge limiters consist of non-linear resistors (metal-oxide varistors SIOV) and a series-connected spark gap. During installation it must be observed that the surge limiter is fl exibly mounted on one side for mechanical reasons.

Dielectric strength in reference to site altitude
The dielectric strength of air insulation decreases with in-creasing altitude due to low air density. The rated lightning impulse withstand voltage values specifi ed in the chapter “Technical Data” apply to a site altitude of 1000 m above sea level. For an altitude above 1000 m, the insulation level must be corrected according to the opposite diagram.
The characteristic shown applies to the rated short-duration power-frequency withstand voltage and the rated lightning impulse withstand voltage.
To select the devices, the following applies:
U ≥ U0 x Ka
U Rated withstand voltage under standard reference atmosphereU0 Rated withstand voltage requested for the place of installationKa Altitude correction factor according to the opposite diagram
A control transformer must be specifi ed accordingly.
Adjustment of the operating mechanism to the site altitude
The contactor-fuse combination is adjusted to a standard site altitude of -200 m to +1250 m. For operation at a different altitude, other site altitudes can be adjusted at the factory from -1250 m to +4000 m (for selection, see “Additional Equipment” on page 23).
Example
For a requested rated lightning impulse withstand voltage of 60 kV at an altitude of 2500 m, an insulation level of 72 kV is required as a minimum under standard reference atmosphere:
72 kV ≥ 60 kV x 1.2

Equipment SelectionSelection aids
Selection aids
The contactor-fuse combination is selected in two steps:
1) The basic device is selected in accordance with the re-quirements of the medium-voltage system and the switch-ing duty.
2) Selection of a suitable fuse.
Generally, fuses of any manufacturer can be used, if they fulfi l the standard IEC 60282-1, IEC 60644 and IEC 60787. The selected fuse must contain a thermal striker of the “medium” type.
But we advise to use our Siemens 3GD2 HV HRC fuse-link for our contactor-fuse combination. For more Information see Catalog HG 12.31, Order No. E50001-K1512-A311-A2-7600 (available as of 2011).
Transformer protection
HV HRC fuses as short-circuit protection for transformers
DIN VDE 0670 Part 402 achieved a standardization of the HV HRC fuse characteristics – referring to their rated current. This results in a protection recommendation for distribution transformers which is widely independent of the fuse manu-facturer.
A minimum or maximum fuse current rating is assigned to each transformer. This larger range provides improved dis-crimination coordination both towards the low-voltage side and the superior medium-voltage side.
Moreover, there are further requirements for special applica-tions, which are described in the relevant standards.
Inrush current
For the specifi ed ratings of distribution transformers, the effects of inrush currents (I2t-values) on the upstream HV HRC fuses have been checked. The most important factors of infl uence are the rated power, vector groups and impedance voltages of the transformers.
According to IEC 60787, Clause 4, the pre-arcing time char-acteristic of the fuse at a time of 0.1 s must feature a cur-rent value greater than 10 to 12 times the rated transformer current.
Short-circuit protection on the low-voltage side of thetransformer
When there is a short-circuit on the low-voltage side at the transformer terminals, a damped short-circuit current fl ows on the high-voltage side:
Ik = IrT 100 Uk
Ik Sustained symmetrical short-circuit currentIrT Rated current of the transformerUk Relative impedance voltage (%)
The HV HRC fuse used breaks this damped short-circuit cur-rent safely. Its minimum breaking current must therefore be lower than the fault current to be expected.
Discrimination requirements between HV HRC fuses
In individual cases, e.g. in line systems with widely separated substations, the discrimination of series-connected HV HRC fuses may be important for operational reasons. The superior HV HRC fuse must have a higher pre-arcing I2t-value as the operating I2t-value of the subordinate fuse.
Discrimination requirements between HV HRC and LV HRC fuses
When the associated LV HRC fuse is selected, discrimination to the HV HRC fuse must be ensured. This equally applies if the low-voltage feeder contains several parallel fuses.
In the case of LV HRC fuses with different current ratings, the fuse with the maximum current rating is decisive for dis-crimination considerations.
Discrimination requirements between HV HRC fuses and low-voltage circuit-breakers
Discrimination must be ensured by means of the time-cur-rent characteristics of the HV HRC fuse-link converted to the low-voltage level and the total breaking time of the provided circuit-breaker.
Motor protection
HV HRC fuses as short-circuit protection of motors
HV HRC fuses are used for short-circuit protection in combi-nation with vacuum contactors.
Due to the arising motor starting current, the instant when the motor starts represents the maximum stress for the HV HRC fuse. This stress must neither operate nor pre-damage the fuse. Other factors of infl uence on the stress of the HV HRC fuses are the starting time and the starting frequency.
The indications of the fuse manufacturer regarding motor protection must be generally observed.
As a guide value for 2 to 6 starts per hour (max. 2 shortly after each other), the pre-arcing current of a fuse to be se-lected must be at least twice the motor starting current for the given starting time. For a higher number of starts, a fuse of the next higher level must be selected.

Equipment SelectionSelection aids
Coordination of the HV HRC fuse with other components of the motor circuit
The high-voltage motor is selected for the corresponding duty. Thus, the following motor data are known:
Rated current• Rated voltage• Starting current• Starting time• Starting frequency•
Coordination of the components of the motor circuit:The time-current characteristic must be located on the •
right of the motor starting current (point A). The rated current of the HV HRC fuse-link must exceed the •
normal current of the motor.The current corresponding to the intersection B of the •
HV HRC fuse-link characteristic and the characteristic of the overcurrent-time protection must be higher than the minimum breaking current of the HV HRC fuse-link. If this is not feasible, it must be ensured that overload currents that are smaller than the minimum breaking current of the HV HRC fuse-link are interrupted by the vacuum contactor via the striker. This prevents thermal overloading of the HV HRC fuse-link, which would otherwise be destroyed.
The rated breaking current of the vacuum contactor must • be higher than the minimum breaking current of the HV HRC fuse-link, and higher than the current resulting from the in-tersection B of the HV HRC fuse-link and the overcurrent-time protection characteristics.
The maximum let-through current • ID of the contactor-fuse-combination shall be limited trough the HV HRC fuse-links (one or two in parallel).
The integral of the square of the current over a given time • interval (I2t-value) is a measure for the thermal short-time stress of the elements of a circuit. The pre-arcing I2t-value of the fuse to be selected must not exceed the maximum permissible I2t-value of the contactor-fuse combination.
The thermal power loss of the HV HRC fuse-links shall not • exceed the maximum value of the contactor-fuse-combination.With integrating the CFC into a panel a reduction though decreased ventilation has to be taken into account.
The contactor-fuse combination 3TL6 is optimized regarding • current integral and power losses for using Siemens HV HRC fuse-links 3GD2 in accordance with the selection on page 13.

Equipment SelectionOrdering data and confi guration example
Order number structure
The contactor-fuse combinations consist of a medium-volt-age and a low-voltage part. The relevant data make up the 16-digit order number. The medium-voltage part covers the main electrical data of the contactor. The low-voltage part covers the auxiliary devices which are necessary for operat-ing and controlling the contactor-fuse combination. Fuse-links must be selected separately.
Order codes
Individual equipment versions are explained more in detail by an order code. Several order codes can be added to the order number in succession and in any sequence.
Mounting parts and special versions ( )
In case of special versions, “- Z” is added to the order num-ber and a descriptive order code follows. If several special versions are required, the suffi x “- Z” is listed only once. If a requested special version is not in the catalog and can there-fore not be ordered via order code, it has to be identifi ed with Y 9 9 after consultation.
The agreement hereto is made between your responsible sales partner and the order processing department at the Switchgear Factory in Berlin.
Confi guration example
In order to simplify the selection of the correct order number for the requested contactor-fuse combination, you will fi nd a confi guration example on each page of the chapter “Equipment Selection”. For the selection of auxiliary voltages, additional components, width across fl ats, etc. the last example of the primary part is taken over and continued, so that at the end of the equipment selection (page 23) a completely confi gured contactor-fuse combination results as an example.
On the foldout page we offer a confi guring aid. Here you can fi ll in the order number you have determined for your contactor-fuse combination.
