China Circuit Breaker Manufacturer, Supplier, Factory

The Differential Current Circuit Breaker RCBO is a device specially designed to detect and cut off fault current in a circuit due to leakage. When the leakage current in the circuit reaches or exceeds a preset value, the RCBO will automatically trip, thus cutting off the circuit and preventing electrical fires and electrocutions.

The 4P 40A/10mA Residual Current Circuit Breaker is a residual current circuit breaker with 4 poles (i.e., 3-phase Fire and Zero wires) that is rated at 40 amps and is capable of automatically cutting off the circuit when the residual current in the circuit is detected to be at or above 10 milliamps. The device is mainly used to prevent electrical fires and electrocution accidents and to safeguard personal and equipment safety.

The DC MCB Miniature Circuit Breaker is an electrical switch specially designed for automatic operation in DC circuits. Its main function is to protect automatic devices from overloads, short circuits, and other fault hazards, and to ensure the safety of the entire power system. When the current flowing through the circuit exceeds the rating of the DC MCB, or when leakage current is detected in the circuit, the DC MCB will automatically disconnect the circuit, thus preventing the circuit from being damaged due to overload, short circuit, or leakage.

The AC/DC Moulded Case Circuit Breaker is an electrical switch with integrated overload protection, short-circuit protection and (in some models) earth leakage protection. It is designed with a molded case, featuring a compact structure, high protection level and long service life. When the current in the circuit exceeds the rated current of the circuit breaker or when a short circuit occurs, the circuit breaker will automatically trip and cut off the circuit, thus preventing the circuit and equipment from being damaged due to overload or short circuit.

STV-63 series WiFi circuit breaker is a multi-function intelligent switch that integrates the functions of electricity metering,overload, short circuit, over and under voltage, leakage, over-temperature protection, remote opening and closing, timing,network communication and so on. It can be widely used in smart power management places such as commerce, agriculture,schools, hospitals, hotels, entertainment places, stations, cultural relics protection units, urban street lamp management andcontrol, and can also be widely used in energy consumption management in industrial and mining enterprises, office buildings and other places.

1P+N Electronic Type RCBOis a special type of circuit breaker which utilizes the electromagnetic principle to detect and cut off the residual current (leakage current) in the circuit, thus preventing electrical fires and personal electric shock accidents. At the same time, it also has an overcurrent protection function, which can automatically cut off the power supply when the circuit is overloaded or short-circuited to protect the safety of the circuit and equipment.
