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.

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.

4P 63A /30mA RCD AC Type

This 4P 63A /30mA RCD AC Type triggers the RCD's internal disconnecting mechanism, causing the RCD to quickly cut off the power supply, thus protecting the safety of electrical equipment and personnel.

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.

63A/100mA Residual Current Circuit Breaker RCCB

63A/100mA Residual Current Circuit Breaker RCCB is the current in a circuit other than the normal operating current, which may be generated due to equipment insulation damage, personnel electric shock, or ground faults, etc. The main function of the RCCB is to quickly cut off the circuit when the residual current is detected as exceeding a preset value, thereby preventing electric shock accidents and electrical fires.

Electronic Magnetic A Type RCCB 125A/30mA

Electronic Magnetic A Type RCCB 125A/30mA is able to detect residual currents in circuits due to leakage, short circuits or ground faults and automatically cut off circuits when the current exceeds a preset threshold, thus protecting the safety of personnel and equipment. Its working principle is based on the principle of electromagnetic induction, when the residual current passes through the transformer, the corresponding magnetic flux will be generated, which in turn triggers the electronic circuit to carry out signal processing, and ultimately controls the action of the release mechanism.
