The leakage circuit breaker is an important electrical protection device, mainly used to detect and cut off leakage faults in circuits. The following are several characteristics of earth leakage circuit breakers:
— Detect leakage faults: The leakage circuit breaker can sense leakage faults in the circuit due to insulation damage or other reasons. It detects offline current, known as leakage current, by monitoring the difference in current flow.
— Quickly cut off the circuit: Once the leakage circuit breaker detects that the leakage current exceeds the preset safety threshold, it will quickly cut off the circuit to avoid dangers such as electric shock accidents and fires.
— High sensitivity: Leakage circuit breakers usually have high sensitivity and are able to detect very small leakage currents, usually in the range of a few milliamps (mA). This makes them effective in protecting personal safety.
— Adjustable operating current: Earth leakage circuit breakers usually provide adjustable operating current settings to adapt to the requirements of different electrical equipment and circuits. Users can adjust it as needed to better match specific application scenarios.
— Reliability and stability: Earth leakage circuit breakers are designed to have a high degree of reliability and stability. They are rigorously tested and certified to ensure they work properly and provide long-lasting protection in a variety of environmental conditions.
— Multi-level protection: Some leakage circuit breakers also have multi-level protection functions. In addition to detecting and cutting off leakage current, they can also provide additional overload and short-circuit protection to further enhance the safety of the circuit.
— Generally speaking, the leakage circuit breaker is an important electrical protection device that can promptly detect and cut off leakage faults in the circuit, effectively protecting personal safety and the integrity of electrical equipment.
