Fuse Selection Recommendations

Selection of The Voltage Rating UnThe voltage rating Un of a semiconductor fuse should be larger than the line to line voltage Uline to line and

fault voltage Ufault:

Un > Uline to line & Un > Ufault

In regenerative DC drives, Ufault is higher than Uline to line;

Faults are not always with an AC voltage (inverters & regenerative DC drives);

Examples: Generally, the fuse voltage rating Un should satisfy the following conditions.

Fuse complying withIEC 60269

For most ratings 1.06 Un ≥ Uac max

For some ratings 1.1 Un ≥ Uac max

For some 690V fuses 1.05 Un ≥ Uac max

Fuses complying with UL248 only Un ≥ Uac max

Note: Uac max is the max R.M.S. value of the line to line voltage.Uac max = rated voltage + possible variation (usually +5% to 10%).

Selection of The Current Rating InThe current rating of the fuse In should be larger than the R.M.S. value in the circuit.

In ≥ IR.M.S.

Corrective coefficients should be taking into account for some special conditions:

ambient temperature inside the cubicle;

cooling;

size of cables or bars connected to the fuse;

variations of the current;

What’s more, a suitable melting curve at 15ms would be required while coordinating with a circuit breaker.

A fuse rating larger than that calculated from the R.M.S. value of the current would be required in such

coordination.

Selection of The Total I2tThe total I2t should be less than that of the semiconductor junction and the semiconductor case rupture:

Total I2t of the fuse < I2t of the semiconductor junction

&

Total I2t of the fuse < I2t of the semiconductor case rupture

A lower voltage is always selected in real application. In this case, the total I2t would be reduced as the

current limiting action is more effective.

Selection of The Arc Voltage The peak arc voltage of the fuse should be less than the reverse voltage of the semiconductor. Generally, a

curve of maximum peak arc voltages VS applied voltage would be required while considering the arc voltage.

Selection for Circuit with Overload Current“Overload” is generally used for excess current flowing in a circuit which is electrically sound. Overload

currents are usually not much greater than the normal full-load current of the system. As a rough rule, the

overload current is less than 8 or 10 times the current rating.

The imposed max overload current Imax is related with the duration and the frequency of occurrence. While

select a fuse for the application, it is helpful to utilize the time/current curve of the fuse and the formula “Imax

< factor % It”. It can be read from the time/current curve for a certain time t. The general guidelines are

listed as follow:

Frequency of OccurrenceOverloads

> 1 sec < 1 sec

Less than once per month Imax < 80% It Imax < 70% It

Less than twice per week Imax < 70% It Imax < 60% It

Several times per day Imax < 60% It Imax < 50% It

Selection of The Breaking CapacityThe breaking capacity of the fuse IR should be higher than the largest R.M.S. value of the short circuit

current Ifault:

IR > Ifault

Selection of The Minimum Interrupting CapacityThe minimum interrupting capacity of the fuse should be higher than the minimum fault current.

Example:Considering a circuit should withstand some occurrence of overload

current and need for short-circuit current protection. Then the VSP

400A700V FS-K would be taken as an example.

VSP 400A700V FS-K is designed according to IEC 60269 (690V), and it is

certificated by UL (700V). The total I2t is 103.6103 A2s, the breaking

capacity is 100kA (700V), the max arc voltage is about 1300V while the

applied voltage is 700V.

Therefore,

the Uac max in a circuit should be less than 1.05690V=724.5V;

the R.M.S. value in the circuit IR.M.S<400A;

the total I2t of the semiconductor junction or the semiconductor case rupture should be larger than 103.6103 A2s;

the short circuit current Ifault should be less than 100kA;

the max reverse voltage of the semiconductor should be less than 1300V while the applied voltage is 700V;

the imposed max overload current Imax should be less than 570A while an overload occurs one time per hour and last

for 60 sec. It is calculated from the expression Imax < 60% It with It read from the time/current curve of VSP 400A700V

FS-K.

While all the situation in the circuit satisfying the above conditions, VSP 400A700V FS-K is the right fuse you are

looking for. If not, try another one.
