1. 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. I2t 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.
