The Restart PRO Autotest residual current circuit breaker (RCCB) carries out an automatic self-test (autotest) at regular intervals, which replaces the manual operation of the test button. The residual current circuit breaker is fully activated during this test without interrupting the system's power supply. If the residual current circuit breaker is triggered, Restart Pro Autotest restores the power supply after an insulation test of the system. If there is a constant system error, no attempt is made to switch on. The system is checked every 2 minutes by RESTART PRO Autotest. If the system assumes a safe value, RESTART PRO Autotest switches the residual current circuit breaker back on. It will not switch on if an error exists. LEDs and an auxiliary contact signal the operating states. RESTART PRO Autotest can be switched on or off using a simple slide switch. Connection (max): 35qmm with insulated plug-in protection, feed at the top. Compatible with the BUS module.
