170M3394 Specialty Fuses 200A 1250V 1*BKN/75 AR CU

This curve gives the peak arc voltage, UL, which may appear across the fuse during its operation as

a function of the applied working voltage, Eg, (rms) at a power factor of 15%.

Power Losses

Watts loss at rated current is given in the electrical characteristics. The curve allows the calculation of the

power losses at load currents lower than the rated current. The correction factor, Kp, is given as a

function of the RMS load current, Ib, in % of the rated current.

Features and Benefits

• Excellent dc performance

• Low arc voltage and low energy let-through (I2 t)

• Low watts loss

• Superior cycling capability

Typical Applications

• DC common bus

• DC drives

• Power converters/rectifiers

• Reduced voltage starters

Description

Square body flush end contact high speed fuses.

Dimensions

See dimensions illustrations.

Ratings:

Volts: — 1250Vac (IEC)

— 1300Vac (UL)

Amps: — 50-1400A

IR: — 100kA RMS Sym.

Agency Information:

CE, Designed and tested to IEC 60269: Part 4, UL Recognized. Consult Cooper

Bussmann for UL Recognition/CSA Component Acceptance status.

Total Clearing I2 t

The total clearing I2 t at rated voltage and at power factor of 15% are given in the electrical characteristics.

For other voltages, the clearing I 2 t is found by multiplying by correction factor, K, given as a function of

applied working voltage, Eg, (rms).
