ADM1L series earth leakage circuit breakers (hereinafter called MM1L ELCB/RCCB), is a new designed MCCB, developed and manufactured adopting international advanced technology. MM1L ELCB/RCCB rated insulating voltage AC 800V is suitable for using in the circuit of AC 50Hz /60Hz, rated voltage 400V, rated working current from16A to 630A to distribute electric power and to protect the line and the equipment from being damaged due to overload, short current and under-voltage. It can also be used for infrequently switch and starting of motor and for motor overload, short circuit and under-voltage protections and can protect the electric appliance from dangerous fire dangerous fire caused by ground faulty current due to the damage of electric appliance insulation. MM1L ELCB/RCCB with the advantages of the small volume, high breaking capacity, short over-arcing, strong anti-vibration and so on. In accordance with the ultimate short circuit breaking capacity classified into two types: Type M (second high breaking), Type H (high breaking).
The breakers could be installed vertically (upright) or horizontally (transverse)
Adverse wiring of terminal is prohibited, in other words terminals "1", "3", "5" only connect to power supply, "2", "4", "6", only connect to load.
