China Circuit Breaker Manufacturer, Supplier, Factory

The high-quality circuit breaker produced by SONTUOEC Supplier is an electrical protective device designed to protect an electrical circuit from damage caused by excessive current, usually caused by overload or short circuit. Its main function is to interrupt the flow of electric current when a fault is detected, preventing damage to the circuit and reducing the risk of fire or electric shock.

4P RCBO AC Type

The 4P RCBO AC Type is a 4-pole circuit breaker that combines residual current protection and overcurrent protection functions, especially designed for alternating current (AC) circuits. It can automatically cut off the power supply when residual current (i.e. leakage current) is detected in the circuit to prevent electrical fires and personal electric shock accidents. At the same time, it also has an overcurrent protection function that can automatically cut off the power supply in the event of an overload or short-circuit in the circuit to protect the safety of the circuit and equipment.

2P 1P+N Residual Circuit Breaker with Overcurrent Protection

The 2P 1P+N Residual Circuit Breaker with Overcurrent Protection is a circuit breaker that combines residual current protection and overcurrent protection. It is capable of automatically cutting off the power supply when residual current (i.e. leakage current) is detected in the circuit to prevent electrical fires and personal electrocution accidents. At the same time, it also has an overcurrent protection function, which can automatically cut off the power supply when the circuit is overloaded or short-circuited to protect the safety of the circuit and equipment.

Electronic Type RCBO

Electronic Type RCBO can connect and break the current in the main circuit, and automatically cut off the circuit when residual current (leakage current) occurs in the main circuit, in order to prevent personal electric shock or electrical fire accidents. At the same time, RCBO also has an overcurrent protection function, which can cut off the circuit when overload or short circuit occurs in the circuit to protect the safety of the circuit and equipment.

2P 63A/30mA RCD AC Type

The operating principle of the 2P 63A/30mA RCD AC Type is based on the residual current transformer. When an unbalanced current (i.e. leakage) occurs in an electrical system, the residual current transformer detects this unbalanced current and generates a magnetic flux proportional to the leakage current. This magnetic flux triggers the RCD's internal release mechanism, causing the RCD to quickly cut off the power supply.
