Type A residual current circuit-breakers detect pulsating direct current and alternating current. Switches in the Selftest Restart design automatically perform a regular function test of the residual current circuit-breaker. This function test occurs without interruption. After tripping, the residual current circuit-breaker is automatically reactivated. The required power supply is integrated. The automatic function can be switched off.

monthly self-test, automatic insulation testing before the restart attempt, no restart attempted if a fault is detected, signalling the operating status by LEDs, configurable auxiliary contact

quick fastening to mounting rail, any installation position, supply from top

The devices can be used anywhere where electrical systems must not be shut down or are difficult to access. These may be, for example, IT and telecommunications systems, agricultural facilities, small wind power stations or sewage treatment plants, Using an optional Modbus interface module, the switching status of the RCCB can be transmitted for remote monitoring.
