Agency Information:
Agency Information: CE, UL Recognized
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.
