China Residual Current Circuit Breaker Manufacturer, Supplier, Factory

Residual Current Circuit Breaker from China SONTUOEC is a switching device that can detect the residual current in a circuit and automatically disconnect it. When the residual current in the circuit reaches or exceeds a preset value, the RCD quickly disconnects the circuit, thereby preventing accidents related to electric shock and fire. In addition to the leakage current protection function, some RCDs also have a short-circuit protection function.

STID-63 RCCB

STID-63 RCCB, full name Residual Current Circuit Breaker (STID-63 RCCB), is an electrical safety device specifically designed to prevent electrical fires and electrocution accidents. It mainly monitors the residual current in the circuit, i.e. the difference between the current of the fire line and the zero line. When this difference (usually caused by leakage) exceeds a preset value, the STID-63 RCCB will automatically cut off the circuit in a very short period of time, thus protecting the personal safety and the equipment from damage.

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.
