FWA 130V:1000-4000A

  
FWA
Specifications
Description: North American style flush-end high speed fuses.
Dimensions: See Dimensions illustrations.

Ratings:
Volts: 130Vac
Amps: 1000-4000A
IR:200kA RMS Sym.50kA @130Vdc
Agency Information: CE, UL Recognized on 1000-2000A fuses

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

Dimensions (in)



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.
