I T
: Hold current: maximum current device will pass without interruption in 20°C still air.
: Trip current: minimum current that will switch the device from low resistance to high resistance in 20°C still air.
V MAX Operating: Maximum continuous voltage device can withstand without damage at rated current.
V MAX Interrupt : Under specified conditions this is the highest voltage that can be applied to the device at the maximum interrupt current.
I MAX Interrupt : Maximum fault current device can withstand without damage at rated voltage.
