High Speed Fuses Square Body US Style -- 690V/700V (IEC): 40-2000A 690V/700V (IEC) 40-2000A 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%. Specifications Description: Square body US style high speed fuses. Dimensions: See dimensions illustration. Ratings: Volts: -- 690Vac (IEC) -- 700Vac (UL) Amps: -- 40-200A IR: -- 200kA RMS Sym. Ag ency Information: CE, Designed and tested to IEC 60269: Part 4, UL Recognized. Consult Cooper Bussmann for UL Recognition/ CSA Component Acceptance status. 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.
