Automatic restart device (ARD) with mounted residual current circuit-breaker (RCCB) for automatically switching on the residual current circuit-breaker again after a trip and with uninterruptible, automatic and regular function test for the residual current circuit-breaker. With automatic insulation testing before the restart attempt. Restart is not attempted if a fault is detected. Integrated, configurable potential-free contact and LEDs for signalling the operating status. With slider for activating/deactivating the restart function.
