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.
