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.

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.

SONTUOEC is one of the Chinese suppliers/manufacturers specializing in the production of various small electrical appliances STRO-40L is mainly used in AC 50Hz(60Hz), rated voltage 110/220V, 120/240V, rated current 6A to 40A low voltage terminal distribution system. RCBO is equal with MCB+RCD function; It is used for electric shock protection and human indirect contact protection, electric equipment protection when human body touching electricity or electric network leak current exceeds stipulated value, and over load and short circuit protection ; It can also be a non-frequency operator in the circuit, wildly used in the residential and commercial district. It complies with standard of IEC61009-1.
