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.

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.
