It may trip between 101% and 145% of rated load, but must trip at 145% at 25°C. Dielectric Strength: Over 1,500 volts RMS. 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. Mechanical/Environmental Data Shock: Withstands to 10g. Endurance Cycling: Over 1,000 cycles at 200% of rated load. Vibration: Withstands to 10g at 10-55 Hz. Weight: Less than 1 1/2 oz. (42.5g).
