STD32LE Series RCBO Residual Current Circuit Breaker 1p+N 40A/30mA

1P+N Electronic Type RCBOis a special type of circuit breaker which utilizes the electromagnetic principle to detect and cut off the residual current (leakage current) in the circuit, thus preventing electrical fires and personal electric shock 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.

Working Principle

 Residual current detection: When there is residual current in the circuit, the zero sequence current transformer in the RCBO will detect this signal and convert it into an electrical signal for processing.

 Signal Processing and Comparison: The detected residual current signal will be amplified, filtered and processed, and then compared with the preset action current value.

 Tripping action: When the residual current reaches or exceeds the preset action current value, the RCBO will trigger the tripping mechanism to cut off the main circuit power.

Features and Advantages

 Electromagnetic principle: Utilizing electromagnetic principle for residual current detection, it is characterized by high sensitivity and fast response speed.

 Multi-functional protection: In addition to residual current protection function, it also has overcurrent protection function, which can comprehensively protect the safety of circuits and equipments.
