Typical power dissipatde from device when in the tripped state in 25℃ still air.

Minimum/Maximum device resistance prior to tripping at 25℃.

maximun ambient operating temperature(Tmao)vs.hold current(Ihold)

Ihold versus tempetature

Trip current:Minimum current at which the device will always trip in 25℃ still air

Maximum Time To Trip Resistance

Hold Current:Maximum current device will not trip in 25℃ still air.

Maximum resistance of device at 25℃ measured one hour after trippde tripping.

Operation beyond the specified rating may result in damage and possible arcing.

Maximum operating volatge device can withstand without damage at ratde current(imax).

Maximum fault current device can withstand without damage at rated voltage(Vmax).
