The Restart PRO Autotest residual current circuit breaker (RCCB) carries out an automatic self-test (autotest) at regular intervals, which replaces the manual actuation of the push-button. During this test, the residual current circuit breaker is completely activated without interrupting the power supply to the system. If the residual current circuit breaker is tripped, Restart Pro Autotest restores the power supply after an insulation check of the system. In the event of a continuous system fault, no attempt is made to switch on the system. Every 2 minutes a system check is carried out by RESTART PRO Autotest. If the system assumes a safe value, RESTART PRO Autotest switches the RCD back on. There is no switching on for an existing fault. LEDs and an auxiliary contact signal the operating status. RESTART PRO Autotest can be switched on or off by a simple switch slide.Connection (max): 35qmm with insulated sub-plug protection, supply at the top. Compatible with BUS + WiFi module.
