Here are some specs on the FWH Series fuses...
FWHSpecificationsDecription:North American style stud-mount fuses.Dimensions:See Dimensions illustration.
Agency Information:CE, UL Recognition & CSA Component Acceptance on 35-800A only (50kA IR@500Vdc). UL Recognition on 35-1200A only, CSA Component Acceptance: 35-1600A.Features and Benefits:
* Excellent dc performance
* Low arc voltage and low energy let-through (I2t)
* Superior cycling capability
* Power converters/rectifiers
* Reduced voltage starters
Data Sheet:35785304 (FWH 35-200A(B) & 900-1600A(A): 500V) 360 (FWH 225-800A: 500V)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.
