General Description & Application


Range 90 ReStart Automatic reclosing devices - In the event of a circuit breaker trip, the ReStart devices, after checking the system status, restore the power supply, thus ensuring maximum continuity of service in maximum safety.


Available for both pure residual current circuit-breakers and those with overcurrent protection, the range is characterized by the Autotest function, with periodic and automatic control of the residual current protection without power interruption, and the PRO function with extended system control.
