BETA Devicesto UL StandardA comprehensive range

UL standards are used in North America, but also in several other countries. This is of particular importance to European exporters of electrical switchgear equipment for machines who export to the USA, as their products will only be accepted if they meet the relevant UL standards. UL 508A describes the design of switchgear cabinets and implementation of integral components with reference to other pertinent UL standards where applicable. It therefore represents the basic standard for all electrical systems used in North America. Countless BETA devices comply with UL standards and are therefore suitable for implementation worldwide in both IEC/EN and UL applications within the framework of their specified use.

Overview of IEC – UL standards

The EN/IEC or UL standards are used worldwide as follows:

Circuit protection systems

Information on UL 508A

The UL 508A "Standard for Industrial Control Panels" is an authorative description for the use of electrical devices and components in control cabinets and is also used by UL for the approval of switchgear.

Fuse protection systems

Low-voltage systems in the USA

While a variety of different systems are used in the USA, 3-phase systems with 240 V and 480 V and 3 and 4-wire systems are the most common, with 208 V and 600 V playing a considerably smaller role.

Residential buildings are primarily fitted with 120 to 240 V single-phase systems. A frequency of 60 Hz is standard in North America.

1) Y describes the "Solidly grounded circuit". The "Y" value specifies the voltage between the phases (e.g. 480 V), the value after the slash specifies the voltage between the phase and the grounding (e.g. 277 V at 480 V voltage between the phases).

Explanation of UL symbols

All symbols and descriptions of UL symbols can be found on the Internet: http://www.ul.com/mark/art.htm

General information about UL can be found at: http://www.ul.com

The "UL listed" symbol u is applied to devices that can be installed universally and without further instructions without any restriction of their respective applicability, e.g. contactors to UL 508, miniature circuit breakers to UL 489, ...

The "UL Recognized" symbol U is intended for devices that may only be installed by experts as components, e.g. miniature circuit breakers to UL 1077, time switches to UL 917, SITOR fuses, ...

Symbol Application

UL symbolThis is the most used UL symbol. If a product has this mark, it means that the device samples tested by UL have met the UL safety requirements. These requirements are largely based on the UL standards published by UL. This mark can be found on all types of devices, such as household appliances, computers, fuses, electrical control cabinets, fire extinguishers, life belts and thousands of other devices.

c-UL symbolThis mark applies to the Canadian market. Products bearing this mark have been tested by UL in accordance with the Canadian safety requirements, which vary slightly from the US regulations in some points.

c-UL us symbolThis symbol was introduced at the beginning of 1998. It means that the device bearing this mark complies with both UL and Canadian regulations.

UR, c-UR and c-UR us symbolRecognized Component Mark and Canadian Recognized Component Mark

These symbols are seldom seen by consumers as they are affixed to special components that are part of a larger system or product. These components may have technical or design restrictions.

The Component Recognition symbol can be on a large number of products, such as switches, power supplies, printed boards, switching devices and many other products. Products for Canada have an additional "c".

The c-UR us symbol was introduced in 1998 and means that the marked components meet both the UL and CSA regulations.

UL standard

Terms for individual elements modules of a switchgear to UL 508A

In the illustrated example, the motor circuit is the "power circuit" and must be protected with a protective device to UL 489. The motor control circuit is the control circuit, which is branched from the load side of the branch protective device and serves to control the connected motor switching devices. The branch itself is not regarded as a "branch circuit" and can be protected with either a UL Listed branch protective device, such as a miniature circuit breaker to UL 489 or with a supplementary protective device miniature circuit breaker to UL 1077.

"Branch circuit protection" is the term for a protective device that protects a branch against overcurrents and short-circuits. "Supplementary protection" is the term for protective devices that are additionally installed downstream of branch protection.

"Class 2 control circuits" are devices that have been tested by UL and approved for extra-low voltages. "Class 1 common control circuits" means that no control transformers are used; the voltage corresponds to that of the motor or the load.

"Field wiring" means that the wiring can be installed "in the field" by an electrician without the need for any specially prepared cables.

"Factory wiring", by contrast, means that the devices can only be factory-connected, e.g. when soldered or crimped connections are required.

Product descriptions

5SY4, 5SY6, 5SY7, 5SY8, 5SX, 5SP4 miniature circuit breakers to UL 1077

Miniature circuit breakers serve to protect cables and lines against overload and short-circuit.

Different tripping characteristics are available for the applications described here. The standards EN 60898, DIN VDE 0641-11 and IEC 60898 form the basis for the design and approval of miniature circuit breakers. The devices are also approved to UL 1077 for Supplementary Protection.

When used for industrial applications and for system and plant engineering applications, the miniature circuit breakers can be supplemented by individually mountable additional components, such as auxiliary switches, fault signal contacts, and accessories, such as busbar systems and mounting parts.

5SJ4 . . .-.HG. . miniature circuit breakers to UL 489

Within the sphere of influence of the ANSI (American National Standards Institute), miniature circuit breakers can be used as an all-round solution for protection tasks in distribution boards, control cabinets and control systems to UL 508A as "branch protectors". In particular, they are also approved for the protection of electrical circuits in heating, ventilating and cooling systems (HVAC).

The terminal are suitable for "field wiring". This means that the devices can be installed not only in factory-finished distribution boards and control cabinets, but also on-site in a customer system.

The rated voltage is 240 V AC and 60 or 125 V DC, whereby the 5SJ4 . . .-.HG40 series is designed for 240/120 V AC systems, 1-phase with "same polarity" connection (same potential at the input terminals) and the 5SJ4 . . .-.HG41 series is also designed for 240 V AC systems, 3-phase with "opposite polarity" connection (different potential at the input terminals).

This covers a wide range of protection tasks, both in residential and non-residual buildings, as well as in industry in electrical circuits to NEC (National Electric Code).

The tripping characteristics B, C and D to EN/IEC 60898 have been adapted so that they fall in the permissible tripping range to UL 489, as well as for applications at 25 °C and 40 °C. This means that the devices are approved for use according to both standards. The enclosure dimensions of the devices correspond to DIN format.

This means that both device series are suitable for universal use worldwide to IEC or UL standards.

Class CC fuse links and Class CC fuse holders

Key features of these fuses for industrial applications are their high switching capacity, high current limitation and ultra-compact design.

In order to prevent confusion with the American Midget fuses or European fuses, size 10 x 38 mm, the Class CC fuses are distinguished by a "rejection tip" on the contact cap. This prevents the use of Midget fuses (with lower switching capacity) in Class CC fuse holders. Class CC fuses are used for "branch circuit protection".

The encapsulated fuse holders are tested and designed to the US National Electrical Code NEC 210.20(A) so that in continuous operation only 80 % of the rated current is permitted as operational current. An operational current of 100 % of the rated current (30 A) is only permitted short-time.

The devices are prepared for the inscription labels of the 8WH8 120-7AA15 and 8WH8 120-7XA05 ALPHA FIX terminal blocks.

There are three different series:• Slow characteristic for the protection of control

transformers, reactors, inductances, considerably slower characteristic than the minimum requirements made in the UL standards on Class CC fuses of 12 s at 2 x In.

• Quick characteristic for a wide range of applications, for the protection of lighting systems, heating, control systems.

• Slow, current-limiting characteristic in the event of overload and quick in the event of short-circuit and high current limitation for the protection of motor circuits.

SITOR fuse links

SITOR fuse links protect converter equipment and the power semiconductors used in these devices (diodes, thyristors, GTOs, etc.) against short-circuits.

There are three operational classes; aR, gR and gS, with the following special features with regard to overload protection.

When using SITOR fuse links of operational class aR, the overload protection of converter equipment, up to approx. 3.5 times the rated current of the fuse link is taken from conventional protective devices (e.g. thermal-delayed overload relays) or, in the case of controlled power converters, from the current limiter, as the tripping characteristics of the fuse do not cover this current range.

SITOR fuse links of operational class gR protect according to their characteristics, even against overload.

As semiconductor protection, SITOR fuse links of operational class gS are also suitable for the overload and short-circuit protection of cables, lines and busbars.

Fuses allied with LV HRC fuses (with contact pins to IEC 60269-2 and slotted contact pins with gauge 110 mm to IEC 60269-4) can be used in 3NH LV HRC fuse bases or in 3KL and 3KM switch disconnectors with fuses and 3NP fuse switch disconnectors.

Due to the higher power dissipation of SITOR fuses compared to standard LV HRC fuses for line protection, it is sometimes necessary to reduce the rated current of the fuse. Always ensure compliance with the configuration and derating information.

SITOR cylindrical fuses (3NC1 0, 3NC1 4, 3NC2 2 cylindrical fuses) are suitable for a wide range of industrial applications for semiconductor protection and offer users an extremely compact and flexible solution. They cover the power range up to 100 A. This design is used all over the world and internationally standardized (IEC 60269-3-1).

These SITOR fuse links also have a considerably higher power dissipation as standard fuse links of operational class gG for line protection. For this reason, 3NC1 09, 3NC1 49, 3NC2 29 SITOR fuse holders have been specially developed for high heat tolerance and maximum heat dissipation. These SITOR fuse holders can also be used as switch disconnectors according to the utilization category to IEC 60947.

5TE1 . switch disconnectors to UL 508

The 5TE1 switch disconnectors are available from 100 A to 200 A in 3- and 4-pole versions and can be used as main switches, repair switches, outgoing feeder switches, as well as emergency system interrupters. The series corresponds to the requirements of IEC 947-3 and its key features are its compact and robust design, high short-circuit strength, high DC switching capacity and comprehensive accessories. Its small footprint means it is easy to install in all types of enclosures, distribution boards and control cabinets. The devices are KEMA certified and approved to UL 508.

According to UL 508, the products are approved as "manual motor controllers", assigned to the category "industrial control equipment" and may be used as switches downstream of branch protection. These systems are designed for use in conventional locations as specified in the "National Electrical Code, NFPA 70" or "Industrial Control Panels Standard, UL 508A".

5TT5 7 Insta contactors to UL 508

Insta contactors are standard devices in installation technology and belong to the BETA switching device range. Insta contactors are particularly suitable for switching heating, lighting and motors. Insta contactors are increasingly used in industry for motors where distribution technology plays a major role, e.g. in auxiliary installations for heat pumps and air conditioning technology. In addition to their basic function, they can also be used to switch single-phase and three-phase electrical motors on and off.

5TT5 7 Insta contactors are approved to UL 508 as "magnetic motor controllers" and are assigned to the category "industrial control equipment". This includes industrial control devices and accessories for starting, braking, controlling or protecting electrical motors, etc. also industrial control devices or systems that store or process information.

5TE6 804 socket outlets for distribution board mounting to UL 498

The socket outlets for mounting in distribution boards to DIN 43880 and on standard mounting rails to DIN 50022 have since become standard in modern switchgear/distribution boards. They are used for tasks such as the connection of plug-in communication devices in communication distribution boards, in switchgear for maintenance purposes or in private plants for the occasional use of devices with heavy starting and separate fusing

To make installation easier, the touch-protected terminals L, N and PE are located on the side of the socket outlet.

The 5TE6 804 socket outlet is approved to UL 498 as a "receptacle for plugs and attachment plugs - component".

7KT58 time and pulse counters to UL 863

Time and pulse counters are used for the reliable monitoring of production and service times, which enables the exact planning and monitoring of production sequences, maintenance cycles and warranty times. As well as the proven electromechanical time and pulse counters for mounting in distribution boards, we also supply digital time and pulse counters. The fields of application for both counter types are very diverse, such as the recording of operating hours of machines, systems or building management systems, as well as pulse counting for general volume flow counting, registration of starting frequencies, starting cycles or production quantities in systems and machines. As well as a modern design, the electronic counter has a 7-digit LCD, which can be reset electrically or manually. What is particularly interesting is that a single device can cover a universal voltage of 12 ... 150 V DC and 24 ... 240 V AC. Both counter versions - with drum-type counter mechanism or LCD - comply with VDE 0435-301 or EN 60255-6 and are approved according to UL 863 and CSA C22.2 No.6.

Time and pulse counters are assigned to "time-indicating and -recording appliances" according to UL 863. The UL 863 includes electrically operating timers that are designed primarily for industrial installations.

7LF4 4 digital time switches and 7LF5 3 analog time switches according to UL 917

These days, energy saving through time switching has become a matter of course. In fact, it is now hard to imagine many process sequences without time switching. The new generation of digital time switches have a much more diverse range of functions than earlier devices and, thanks to better solutions, are simpler to operate. They can be used for switching systems or system components, or for functions, such as: • Irrigation systems • Greenhouses • Public gardens • Swimming pools • Filtering installations • Canopy controls • School bells • Church bells • Shop window lighting • Advertising lighting • Gym lighting • Street lighting • Street lighting • Office lighting • Lighting of stairwells and entrances • Preheating of industrial furnaces and spraying machines • Heating and air-conditioning systems • Fans and ventilation systems • Heating and circulation pumps or • Sauna systems.

All devices have the VDE mark and approval to UL 917 and CSA-C22.2 No. 14. Devices with voltage variations from 120 V AC are also available especially for use according to UL.

The requirements specified in the UL 917 "Standard for safety for clock-operated switches" cover time-controlled clocks with a rated voltage of 600 V, which are designed for switching loads at specific intervals and are intended for use in accordance with National Electrical Code, ANSI/NFPA 70.
