Abstract
A circuit breaker having a housing structure with accessory devices for power circuit breakers, which housing structure can essentially eliminate the need for complex and expensive methods for the insertion and positioning of the accessory devices in the main housing of the power circuit breaker. For that purpose, in the rear portion of the narrow side walls of the accessory housing enclosing an accessory device, there are first rigid guide and retaining members and second rigid retaining members located opposite one another, interacting with these members are a rigid third guide and retaining member and a flexible fourth retaining member, which are located in a recess of the top part of the main housing, which recess contains the accessory housing or housings. Actuator elements of the accessory devices, if any, and the corresponding bottom actuator openings in the recess interact as second and third guide members.
