It is recommended that users also seek out the pertinent approvals files of the agencies/laboratories and review them to ensure the product meets the requirements for a given application. Electrical Data +25C Mechanical/Environmental Data Calibration: Breaker will continuously carry 100% of rated load. It may trip Shock: Withstands to 10g. between 101% and 145% of rated load, but must trip at Endurance Cycling: Over 1,000 cycles at 200% of rated load. 145% at 25C. Vibration: Withstands to 10g at 10-55 Hz. Dielectric Strength: Over 1,500 volts RMS. Weight: Less than 1 1/2 oz. (42.5g). Maximum Operating Voltages: 50VDC 250VAC. Interrupt Capacity: 2,000 amps at 50VDC (0.5 - 30 amp models). 1,000 amps at 250VAC (0.5 - 30 amp models). Note: 30 0amp model not UL or CSA. Resettable Overload Capacity: Ten times rated current.
