Typical power dissipatde from device when in the tripped state in 25℃ still air environment at rated voltage Maximum Time To Trip Maximum operating volatge(Vdc) device can withstand without damage at ratde current(Imax). Maximum interrupt volatge(Vac) device can withstand without damage at ratde current. Maximum fault current device can withstand without damage at rated voltage. Resistance Hold Current:Maximum current device will not trip in 25℃ still air. Trip current:Minimum current at which the device will always trip in 25℃ still air K250-200U Part number K250-040U K250-060U Maximum device resistance prior to tripping at 25℃. Maximum device resistance one hour after it is trippde at 25℃ . Operation beyond the specified rating may result in damage and possible arcing.
