The present invention provides a residual current breaker with over current protection (RCBO), comprising a first housing enclosing a miniature circuit breaker (MCB) and a second housing separated from the first housing by a main frame.

A residual current safety switch has a residual current transformer (3) connected to an evaluation circuit (5) that controls an electromagnetic trigger (K1) for actuating switching contacts (1, 2).

The present invention provides a residual current breaker with over current protection (RCBO), comprising a first housing enclosing a miniature circuit breaker (MCB) and a second housing separated from the first housing by a main frame.

The invention relates to a control unit for safely re-enabling a ground fault interrupter, and a corresponding ground fault interrupter.

The residual current device may be a combination of various components that detect the residual current and turn the main circuit current on and off.

The protection consists of a 16A circuit breaker and a 30mA differential circuit breaker.

On the one hand, you’ve got an automatic differentiator.

The invention relates to a power circuit-breaker, especially a differential current circuit-breaker, comprising a summation current transformer (6) which monitors a supply network (Ln).

Protective devices controlled by differential (residual) current

The aim of the invention is to integrate a differential current triggering device (8) into a line protection switch (11) while maintaining the line protection switch components (1 - 6).

RCBO stands for residual current circuit breaker with overload protection.

the safety switch disconnects the circuit it protects.
