Floor-Mounted 3 Guns DC EV Charger

Monitors the electrical system and in the event of a fault automatically disconnects all poles including the earth conductor. If the user uses an EV charger equipped with PEN protection, its internal design has a contactor to cut off the ground, once the PEN line is cut off, the contactor KM1 and KM2 are immediately and automatically disconnected, there is only a weak leakage current between CP and PE to L line, its current value is less than 1mA, which is the smallest perceived leakage current of the human body, people can disengage themselves, no safety risks.
