Specifications Description: High speed fuses for the protection of DC circuits in equipment. Dimensions: See dimensions illustration. Ratings: • Volts: 2000Vdc Amps: 20-125A • IR: —2000Vdc = 100kA, L/R: 15 ms . Agency Information: Consult Cooper Bussmann Electrical Characteristics 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 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.
