Differential Current Circuit Breaker RCBO

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.

DC MCB Miniature Circuit Breaker

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.

AC/DC Moulded Case Circuit Breaker

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.
