Single Pole Rccb Switches

China suppliers CNKA offers classy single pole RCCB switches. These switches not only control the on/off function of the main circuit like other circuit breakers but also detect and assess leakage current. If leakage or insulation damage occurs in the main circuit, the single pole RCCB switches will control the circuit based on the detected issue. They can be used alongside fuses and thermal relays to create a comprehensive low-voltage switching solution.

CNKA single pole rccb switches Main structure

Leakage protectors offer unmatched sensitivity and rapid response for electric shock and leakage protection compared to other devices. Unlike fuses and automatic switches, which must be set above normal load currents to avoid false tripping and primarily protect against phase-to-phase short circuits and sometimes overloads, leakage protectors react by detecting the system's residual current. During normal operation, the residual current is nearly zero, allowing the leakage protector to be set to a very low action protection value (usually in milliamps). When a personal electric shock or a fault with live equipment occurs, resulting in a significant residual current, the leakage protector quickly detects this and acts to cut off the power supply.

CNKA single pole rccb switches FAQ

Q: What does RCD mean?
A: A Residual Current Device (RCD) is designed to disconnect the main circuit when it detects a certain level of residual current under normal operating conditions. It detects residual currents and acts as a trigger to turn the circuit on or off, helping to prevent electric shocks caused by ground faults or other electrical issues.

Q: What is the difference between RCD and RCCB?
A: RCD stands for Residual Current Device, while RCCB stands for Residual Current Breaker. An RCCB is specifically an electrical device that immediately disconnects the circuit upon detecting current leakage to the earth wire.

Q: Which is better, RCD or RCBO?
A: An RCBO (Residual Current Breaker with Overcurrent protection) integrates both circuit breaker functionality and residual current detection, offering added protection. In contrast, an RCD (Residual Current Device) only provides leakage protection. RCBOs are better suited for applications where additional protection is needed, particularly in circuits with a higher potential for fire hazards.
