1. Interrupting ratings were measured at 100% (⁄Ω¡§ to 5) and 100% (7, 10) power factors on AC, and a time constant less than 1ms. on D.C.
2
2. I t was measured at 50 amps 125 VAC, .95PF, (random closing angle) and 300 amps 125 VDC, TC <1ms. for ⁄Ω¡§ through 5 amps and 50 amps 60 VAC, .95PF, (random
closing angle), and 300 amps 90 VDC, TC <1ms. for the 7 and 10 amp fuses.
