Electrical Data @ +25°C
Calibration: Breaker will continuously carry 100% of rated load. 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 amp 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).

To use this chart: Read up from the ambient
temperature to the curve, and across to find a correction
factor. Multiply the breaker rating by the correction
factor to determine the compensated rating. Calculate
the overloads in terms of the compensated rating to use
the published trip curve.
