Dimensions–mm

1. Vmax: Maximum continuous voltage the device can withstand without damage at rated current

2. Imax: Maximum fault current the device can withstand without damage at rated voltage

3. Ihold: Maximum current the device will pass without interruption at +23 °C still air

4. Itrip: Minimum current that will transition the device from low resistance to high resistance at

+23 °C still air

5. Pd: Power dissipated from the device when in tripped state at +23 °C still air

6. R

i: Minimum resistance of the device at +23 °C

R

1: Maximum resistance of the device one hour after tripping at +23 °C
