A circuit breaker is for interrupting an electric circuit if settable protective parameters are exceeded. In an embodiment, the circuit breaker includes an electronic trip unit, in which the set protective parameters are stored, with a movable sealing pane, which covers at least part of the circuit breaker. The circuit breaker further includes a sensor with which a first state of the sealing pane can be ascertained. The electronic trip unit is designed such that changes to the protective parameters are accepted by the electronic trip unit only in the first state of the sealing pane.

Circuit breaker

A protective circuit breaker includes a switch housing; connection pieces; a switching contact arranged in the switch housing and connected to the connection pieces; a converter housing including a first passage opening and inserted into a recess in the switch housing and through which the second connection piece runs; a converter coil being arranged around the passage opening/the second connection piece; a plate-like converter cover including a second passage opening through which the second connection piece extends. In order to permit a simple voltage tap, in an embodiment the converter cover has arranged on it: a first contact bearing against the second connection piece at the converter cover, a second contact electrically connected to the first connection piece, and a third contact connected to the first or a second electronics system. An electrical connection is included, via which the third contact is selectively connectable to the first or second contact.

Protective circuit breaker

A rotor shaft module for a rotor shaft of a molded-case circuit breaker, includes a module body including an electrically insulating first material, the module body including a receptacle for a contact element of the molded-case circuit breaker. The rotor shaft module includes at least one coupling apparatus for connection to an opposing coupling apparatus of a further rotor shaft module. In addition, disclosed are a rotor shaft for a molded-case circuit breaker includes at least two coupled rotor shaft modules; a molded-case circuit breaker including a rotor shaft; and a method for producing a rotor shaft module for a rotor shaft of a molded-case circuit breaker.
