摘要： A thermal overload trip apparatus capable of minimizing inferiority caused by a variation when manufacturing an adjusting means and simply adjusting sensitivity by duplicating the means for adjusting a sensitivity of a trip operation current, comprising, a trip mechanism driven to a trip position by a driving force from a shifter mechanism on occurrence of an overload on a circuit; a release lever mechanism for driving the trip mechanism to the trip position by pressing it when there is the driving force from the shifter mechanism or for releasing the trip mechanism when there is no driving force, on occurrence of the overload on the circuit; an adjusting lever for operating the release lever mechanism to be horizontally moved by rotation; an adjusting knob having an upper surface having a setting groove and a lower portion having a cam portion; and a means independently adjusting the sensitivity of the trip operation current regardless of manipulating of the adjusting knob.
