Abstract
A particular overload protection is provided for a circuit which is normally closed by an electromagnetic circuit breaker energized by a relatively low level holding current. The overload protection is particularly provided through an auxiliary electromagnetic system connected to be responsive to the current in the circuit governed by the circuit breaker whereby the auxiliary electromagnetic system includes an armature carrying a plunger penetrating the circuit breaker such that upon occurence of an overload the auxiliary electromagnetic system is energized and its plunger pushes the armature of the circuit breaker into a contact opening disposition.
