Electrical Characteristics

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.

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
