China Earth Leakage Circuit Breaker Manufacturer, Supplier, Factory

The working principle of Earth Leakage Circuit Breaker(ELCB) is current balance. Under normal circumstances, when the currents in the phase and neutral wires of the circuit are equal and opposite, a current balance is formed. When a leakage or abnormal current occurs in the circuit, the current balance between the phase wire and the neutral wire is disturbed. ELCB can quickly detect this change and disconnect the circuit.

1. Main Functions

Leakage protection: When a leakage occurs in the circuit, the ELCB circuit breaker can quickly disconnect the circuit, preventing accidents due to electric shock.

Overload protection: When the current exceeds the rated value, the ELCB automatically disconnects the circuit to prevent equipment damage due to overload.

Short circuit protection: When a short circuit occurs, the ELCB circuit breaker can quickly respond and disconnect the circuit, effectively preventing serious consequences such as fire.

2. Application Scenarios

ELCB is widely used in everyday life, industry, trade and other areas:

3. Importance

The importance of ELCB as a key component of the electrical safety system cannot be overestimated. It not only ensures the safety of circuits and personnel, but also effectively reduces the likelihood of fires and accidents associated with electric shock. With the constant development of electrical technology, the performance and reliability of ELCBs are also constantly improving, providing more reliable electrical safety protection.

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.

Adjustable Current Leakage Circuit Breaker ELCB

Adjustable Current Leakage Circuit Breaker ELCB is a device that can detect leakage in the circuit and automatically cut off the power supply. It is mainly used to protect personal safety and prevent electrical fires. When the leakage current in the circuit reaches or exceeds the preset value, the ELCB can quickly cut off the power supply, thus avoiding electric shock accidents and electrical fires. At the same time, it also has overload and short-circuit protection functions.

Disjuntor Circuit Breaker

Disjuntor Circuit Breaker is a kind of switching device used to protect the circuit, when there is overload, short circuit and other faults in the circuit, it can quickly cut off the circuit to prevent the fault from expanding and damaging the equipment in the circuit. Due to its small size, light weight, easy installation and other characteristics, miniature circuit breaker is widely used in residential, commercial and industrial fields as a protection element for terminal appliances.
