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
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%.
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
multiplying by correction factor, K,
given as a function of applied working voltage, Eg, (rms).
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
