Abstract

A circuit breaker has a threaded collar fixed on a breaker housing and an approximately cylindrical actuating element displaceably guided in a bore of the threaded collar and partially protruding from the breaker housing for manual push-pull actuation in an advantageous way on the actuating side. In order to seal the circuit breaker, a sealing ring seals an annular gap formed between the wall of the bore and the circumference of the actuating element.
