Description Square body flush-end contact high speed fuses, for the protection of DC common bus, DC drives, power converters/rectifiers and reduced rated voltage starters. Catalog numbers come with Type K indicator for use with microswitches. Specifications Ratings • Volts: • 1000 Vac (IEC, 50-1250 A) • 1000 Vac (UL, 250-1100 A) • 900 Vac (IEC, 1400 A • Amps: 50-1400 A • Interrupting rating: 125 kA RMS Sym. Operating class: aR Agency information • Designed and tested to IEC 60269 Part 4 • UL Recognized, E125085, JFHR2 (only sizes 2 and 3 up to 1100 A) • CE 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). 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.
