Interrupting ratings were measured at 100% (1/16 to 5) and 100% (7, 10) power factors on AC, and a time constant less than 1 ms. on DC. 2 2. I t was measured at 50 amps 125 VAC, .95PF, (random closing angle) and 300 amps 125 VDC, TC <1ms. for 1/16 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. NOTE: All values shown above are typical. Device designed to carry rated current for four hours minimum. An operating current of 80% or less of rated current is recommended, with further derating required at elevated ambient temperatures. 0210 BU-SB10142 Page 1 of 2 Data Sheet 2003OBSOLETE - Recommended replacement with MCRW, Data Sheet 4074 - OBSOLETE Subminiature Through Hole MCR Series, Fast Acting, Solid Matrix TIME CURRENT CURVE AMPERE RATING 10 1 .1 .01 .001 CURRENT IN AMPERES PACKAGING CODE Packaging Code Description Blank 10 units BK 500 units TR 2,500 pieces on tape and reel per EIA-296, 52.4mm spacing OC-2544 Rev.
