Restart RM PRO switch-on module for mounting on Gewiss residual current devices (RCBO) of the MDC series. With the RESTART PRO module, the residual current devices are automatically switched back on after they have been triggered. The system is switched back on after an automatic insulation and/or short-circuit test by the RESTART module. If the system is permanently faulty, no switch-on attempt is made. The system is checked every 2 minutes by RESTART PRO. If the system assumes a safe value, RESTART PRO switches the residual current device back on. It is not switched on to an existing faulty device. The power supply is integrated in the RESTART module and is carried out via the cables at the bottom or top of the residual current device without any additional parts. LEDs and an auxiliary contact signal the operating states of the RESTART module. The RESTART module can be switched on or off using a simple slide switch. Rated residual current: 0.03A, type: A, compatible with the BUS module.
