International Classification:

H01H 7306

US Classification:

335202

Abstract:

A narrow molded case circuit breaker having a trip-free overcenter toggle contact operating mechanism wherein the contact operating spring is connected between the movable contact arm and releasable cradle, and the contact arm is pivotally connected to the manual operating member, is constructed in such a manner that prior to closing of the housing by its cover part, the movable contact arm is cocked with respect to the cradle. That is, when the circuit breaker is assembled, the movable contact arm and cradle are mounted for movement is generally parallel planes. However, before the housing cover is assembled to the housing base, the main spring moves the movable contact arm so that the plane thereof is at an angle with respect to the plane of the cradle. In order to limit this tilting or cocking, the cradle is provided with a blocking formation which is engaged by the movable contact arm so that cocking of the movable contact arm is limited to an acceptable degree.
