The CHINT NXBLE-63 4P 30mA Residual Current Operated Circuit Breaker (RCBO) is a safety device that integrates both miniature circuit breaker (MCB) and residual current device (RCD) functionalities. Designed with 4 poles, it's suitable for three-phase electrical systems with a neutral wire, providing comprehensive protection. The 30mA sensitivity rating signifies its ability to detect and respond to even small earth leakage currents, minimizing the risk of electric shock. In addition to earth leakage protection, it also protects against overcurrents and short circuits. The NXBLE-63 is designed for use in residential, commercial, and light industrial applications, offering reliable protection in a compact form factor.
