Description:
Square body DIN 43 653 stud-mount high speed fuses.

Ratings
Volts: 1000Vac (20-250A); 900Vac (315A)
Amps: 20-315A

Agency information:
CE, Designed and tested to IEC 60269: Part 4, UL Recognized.

Electrical Characteristics
Total clearing I2t

The total clearing I2t at rated voltage and at power factor of 15% are given in the electrical characteristics. For other voltages, the clearing I2t is found by multi-plying by correction factor, K, given as a function of applied working voltage, Eg, (rms).

Arc Voltage

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 (I2t)
• Low watts loss
• Superior cycling capability

Typical Applications
• DC common bus
• DC drives
• Power converters/rectifiers
• Reduced voltage starters
