CHINT NB1L-40 2-Pole RCBO 20A 30mA 6kA

NB1L-40 2P C20 30mA A 6kA Differential Circuit Breaker — Comprehensive Electrical Protection

NB1L-40 2P C20 30mA A 6kA is a two-pole Residual Current Circuit Breaker with Overcurrent protection (RCBO) from CHINT, designed to safeguard electrical circuits against overloads, short circuits, and earth leakage currents. Combining the functions of a miniature circuit breaker (MCB) and a Residual Current Device (RCD), it provides comprehensive protection for both people and equipment. Its 30mA sensitivity offers reliable personnel protection, while Type A functionality ensures detection of AC and pulsating DC leakage currents, enhancing overall safety. Ideal for residential and commercial applications.
