Description

technical field

[0001] The invention relates to a coil frame of an electromagnetic circuit breaker for protecting switchgear, which has a first end plate and a second end plate and a hollow cylindrical body arranged between the end plates for accommodating a coil. The invention also relates to a yoke for an electromagnetic circuit breaker for the protection of switchgear, having a U-shaped profile, comprising a base and two arms arranged on the base and a respective recess in each arm for To run through and guide the ejector rod. The invention also relates to an electromagnetic circuit breaker with a protective switching device having a coil former and a magnetic yoke, and to a protective switching device. Background technique

[0002] Protective switching devices enable safe contact with electrical energy. Firstly, the increasing use of fault current (FI) protective switches and line protective switches (so-called LS switches) contributes to increased safety. The combine...
