*No UL/CSA 

Users should thoroughly review the technical data before selecting a product part number. It is recommended that users also seek out the pertinent approvals files of the agencies/laboratories and review them to confirm the product meets the requirements for a given application. 

## **Mechanical/Environmental Data** 

## **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. 

**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). 

**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.
