The device is designed to disconnect the DC circuit, when there is a power outage on the AC side, and automatically switch on the DC circuit, when AC power is restored. Such a situation occurs in the event of a power grid failure, or a deliberate shutdown of the power supply to a building when there is a fire hazard. The ProJoy fire protection circuit breaker does not require resetting and is completely maintenance-free.
