Leakage Circuit Breaker

Leakage Circuit Breaker

Earth leakage protection circuit breaker mainly has the following functions:

Function	Description
Leakage Detection	Detects any leakage current in the circuit.
Automatic Disconnection	Automatically disconnects the circuit when a leakage current is detected.
Protection	Protects against electric shock and fire hazards due to leakage currents.
Reset Capability	Allows for manual reset once the fault has been rectified.
Monitoring	Continuously monitors the circuit for any abnormal leakage currents.

The leakage circuit breaker is extremely sensitive and can accurately capture even the smallest leakage current in the circuit (such as the weak current generated when a person is accidentally electrocuted), eliminating the risk of electric shock caused by leakage from the root and strictly meeting high safety standards. It has an extremely fast response time. Once a leakage current is detected, it can instantly trigger the tripping mechanism to disconnect the circuit, blocking the spread of danger with a millisecond reaction speed, effectively avoiding electric shock injuries or fire accidents caused by leakage. It is also thoughtfully equipped with a manual test function and a dedicated test button on the body, so users can manually check the operating status of the circuit breaker at any time. Inquire

Features of Leakage circuit breaker

DAM1L series residual current (leakage) circuit breaker is a new series of residual current (leakage) successfully developed by using international standard design and advanced manufacturing technology.Protected moulded case type circuit breaker. The rated insulation voltage of circuit breakers of this series is 400V which is mainly used for ac 50Hz and rated In a power distribution network with a current of 10A~500A and a rated working voltage of 380V/400V, it is used to distribute electric energy and protect the overload and short circuit of lines and power equipment.

FAQ

What is a Leakage Circuit Breaker?
>

A leakage circuit breaker is an electrical protection device. Its main function is to detect leakage current in the circuit (when current leaks to the ground) and quickly cut off the power supply within milliseconds, thereby preventing electric shock accidents and avoiding fire hazards caused by leakage.
How does a leakage circuit breaker work?
>

It works by comparing the current of the live wire and neutral wire in the circuit. Under normal conditions, the two currents are equal. When leakage occurs, part of the current flows to the ground, causing the two currents to be unequal. The breaker detects this difference, triggers the tripping mechanism, and cuts off the power immediately.For a more detailed explanation, please read <Working principle of leakage circuit breaker>.
Where is a leakage circuit breaker usually installed and used?
>

It is widely installed in residential electrical systems, such as distribution boxes in homes, to protect household electricity safety. It is also used in industrial and commercial places, such as workshops, shopping malls, and office buildings, especially in circuits connected to electrical equipment that is easily touched by humans.
