Automatic circuit breaker for wide variety of applications. Designed to protect electrical users in residential and non-residential buildings as a part of electrical distribution system, as well as in low-voltage industrial switchgears. AP50B circuit breakers conduct current in regular mode and cut-off current in case of overload or short-circuit, and also can be switched off and on manually.
Device is compliant with GOST 9098-78
