The Restart PRO Autotest Residual Current Circuit Breaker (RCCB) performs an automatic self-test (Autotest) at regular intervals, replacing the need for manual testing. During these tests, 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 event of a persistent system fault, no attempt to reset will be made. Every 15 minutes, Restart PRO Autotest conducts a system check. If the system returns to a safe value, Restart PRO Autotest will switch the RCCB back on. It will not switch on if a fault is still present. LEDs and an auxiliary contact indicate the operating states. Restart PRO Autotest can be turned on or off with a simple toggle switch. Connection (max): 35 sqmm with insulated plug-in protection, top feed.
