ABSTRACT:
A thermal and/or magnetic overload trip device for an electrical switching device having multiple poles includes a housing having a housing member configured to receive a plurality of functional elements and being at least partially closable. The overload trip device further including a conductor strap associated with each of the multiple poles, each conductor strap having an associated housing portion, and a rotatable trip shaft configured to rotate between a rest position and an actuating position so as to trip an associated switching mechanism. The overload trip device further including at least one rotatable adjusting element configured to set the at least one of the presettable thermal threshold and the presettable magnetic threshold. Further, the housing member is configured so that the functional elements is insertable therein and is couplable to the housing member.
