Gewiss GW90943B AUTOTEST 4P 63A 0.03B(IR) 7M (GW90943B)

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 reset will be made. Restart Pro Autotest conducts a system check every minute. If the system returns to a safe state, Restart Pro Autotest will reset the RCCB. It will not attempt to reset if a fault is still present. LEDs and a auxiliary contact indicate the operational states. Restart Pro Autotest can be turned on or off using a simple toggle switch. Maximum connection: 35 sqmm with insulated plug protection, top feed. Compatible with the BUSWiFi module.
