Dimensions: See Dimensions illustration. Ratings: Volts: — 500Vac Amps: — 35-1600A IR: — 200kA Sym. — 50kA @ 500Vdc 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. 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 volt- ages, 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 cur- rent is given in the elec- trical characteristics. The curve allows the calcula- tion 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.
