Description
ProJoy fire switch
is a device for switching on and off direct voltage from photovoltaic panels and is automatically controlled by the alternating current network. The purpose of the device is to disconnect the DC circuit when the AC power is interrupted and automatically reconnect 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 building’s power supply when there is a fire hazard. The ProJoy fire protection switch does not require resetting and is completely maintenance-free. A properly installed ProJoy circuit breaker has a positive opinion of Fire Experts and meets the provisions of the amendment to the Construction Law, which entered into force on September 19, 2020 for installations with an installed electrical capacity of more than 6.5 kW.
