Product details

The Restart Pro Autotest Residual Current Circuit Breaker (RCCB) performs an automatic self-test at regular intervals, replacing the need for manual testing. During this test, the residual current circuit breaker is fully activated without interrupting the power supply to the system. If the RCCB trips, Restart Pro Autotest restores the power supply after conducting an insulation test of the system. In the case of a persistent system fault, no attempt to switch on will be made. Restart Pro Autotest checks the system every minute. If the system returns to a safe state, Restart Pro Autotest will switch the RCCB back on. No activation will occur if a fault is still present. LEDs and a auxiliary contact indicate the operating states. Restart Pro Autotest can be easily turned on or off with a simple toggle switch. Maximum connection: 35 qmm with insulated plug protection, top feed. Compatible with the BUSWiFi module.
