China Suppliers ICHYTI Low Price rcd rccb residual current protection circuit breaker is an electrical device mainly used to detect whether there is a leakage fault in the equipment and protect individuals from the risk of fatal electric shock. It has overload protection and short circuit protection functions, which can be used to protect circuits or motors from overload and short circuit damage. At the same time, rcd rccb residual current protection circuit breaker can also serve as an infrequent switching and starting device for circuits.

ICHYTI rcd rccb residual current protection circuit breaker Parameter (Specification)

ICHYTI rcd rccb residual current protection circuit breaker Characteristic

◉ The leakage protector is mainly used to prevent single-phase electric shock accidents in the human body, that is, when the load side of the leakage protector contacts a phase wire (live wire), it can provide effective protection. But if the human body is insulated from the ground and touches one phase line and one zero line, the leakage protector cannot provide protection.

◉ Leakage protectors may not reflect their importance during normal circuit operation, but their preventive role cannot be ignored. Therefore, when the leakage protector operates, the cause should be carefully identified, rather than simply shorting or removing the leakage protector. This is extremely dangerous and absolutely unacceptable.

ICHYTI rcd rccb residual current protection circuit breaker FAQ

Q: What does Rcbo mean?

A: CHYT RCBO is a circuit breaker that provides leakage protection. The relevant standards that RCBO must adhere to are the international standard IEC 61009-1:2012 and the national standard GB 16917.1-2003.

Q: What is residual current?

A: Residual current refers to the vector sum of current in each phase, including the neutral line, in a low-voltage distribution line that is not zero. Generally, in the event of an accident on the power supply side, the current flows from the charged body to the ground through the human body, causing the magnitude of the current in phase I and phase II in the incoming and outgoing lines of the main circuit to be unequal. At this time, the instantaneous vector composite effective value of the current is called residual current, commonly known as leakage current.

Q: Where is RCCB used?

A: CHYT RCCB is typically installed in conjunction with an MCB to provide protection against overcurrent and short circuit current. Both the phase and neutral wires pass through the RCCB device, which offers highly effective protection against a leakage current of 30, 100, 300mA. This safety mechanism is widely employed to prevent electric shocks.
