Intelligent Residual Current Circuit Breaker RCCB with LCD display


TGM2E2-□Y series residual current circuit breaker (Hereinafter referred to as “circuit breaker”) is the scientific and technological innovation type of products developed by our company according to the power-usage environment of urban and rural power grids of our nation. It combines residual current circuit breaker with moulded case circuit breaker. It is suitable for the circuit with AC 50Hz, 400V rated working voltage, 1000V rated insulation voltage and rated current to 800A power supply system of 3 poles four lines neutral grounding. It can provide indirect protection for body electric shock, and it also can prevent the fire caused by grounding fault current from damage of equipment insulation. It can protect the circuit or power equipment from overload, short-circuit, over-voltage, under-voltage and loss of phase, etc.
