China suppliers ICHYTI Classy single pole rccb switches Quotation not only controls the on/off of the main circuit like other circuit breakers, but also has the function of detecting and judging leakage current. When there is leakage or insulation damage in the main circuit, single pole rccb switches can control the on/off of the main circuit based on the judgment results. It can be used in conjunction with fuses and thermal relays to form a fully functional low-voltage switching element.

◉ The sensitivity and fast response speed of leakage protectors are unmatched by other protective devices in terms of electric shock and leakage protection. Fuses and automatic switches need to be set with action protection values based on load current, and must be set above normal load current to avoid misoperation. Their main function is to cut off phase to phase short circuit faults in the system, and sometimes also includes overload protection functions. In contrast, leakage protectors react and act by detecting the residual current of the system. 

◉ During normal operation, the residual current of the system is almost zero, so the leakage protector can set a very small action protection value (usually mA level). When there is a personal electric shock or a live equipment shell in the system, a large residual current will be generated. The leakage protector will reliably detect and handle this residual current, and quickly act to cut off the power supply.

ICHYTI single pole rccb switches FAQ

Q: What does RCD mean?

A: Residual Current Device (RCD) is designed to switch off the main circuit when a certain level of residual current is detected under normal operating conditions. It incorporates various elements that detect residual current and act as a trigger to turn on/off the main circuit. This device helps ensure the safety of electrical installations by preventing electric shock caused by ground faults or other electrical faults.

Q: What is difference between RCD and RCCB?

A: RCD stands for Residual Current Device, while RCCB stands for Residual Current Breaker. An RCCB is an electrical wiring device that immediately shuts off the circuit upon detecting a current leakage to the earth wire

Q: Which is better RCD or RCBO?

A: The reason for the dissimilarity between these two devices lies in the fact that an RCBO integrates circuit breaker functionality into its design whereas an RCD does not. As such, an RCBO is better suited for applications where added protection is required, particularly in circuits where there is a greater potential for fire hazards.
