FIRE SAFETY FUSE PROJOY MC4 PEFS-EL-40-4

ProJoy PEFS-EL40-4 is a device designed to control the supply of direct current from photovoltaic panels by automatically switching it on and off. It is controlled automatically by the alternating current network. The main purpose of this device is to disconnect the direct current circuit in case of a power outage on the alternating current side and automatically reconnect the direct current circuit after the alternating current supply is restored. This situation occurs in the event of a power failure in the electrical network or intentional power shutdown in the building due to fire hazard. The ProJoy fire protection switch does not require manual resetting and operates completely without the need for maintenance. What truly distinguishes this switch is its significant current carrying capacity - up to 40A at 1000V, as well as the ability to handle two strings (or chains). The PEFS-EL40-4 switch comes equipped with complete MC4 connectors, both those integrated into the device and those that need to be attached to the ends of DC cables. Installation is quick and trouble-free.
