Abstract (en)
An auxiliary device for a magnetothermal circuit breaker, comprising an electrical protection unit that cooperates, by means of a mechanism, with an opening slider biased by a return spring, in order to define a release position, in which the electrical protection unit actuates the mechanism and releases the slider, which acts on the safety opening mechanism of the circuit breaker, and a rearming position, in which the spring is rearmed. The mechanism has a single actuation lever in which a first end cooperates with the electrical protection unit and a second end cooperates with the slider. <IMAGE>
