CHINT NB1L-40 2-Pole RCBO 16A 30mA 6kA

NB1L-40 2P C16 30mA A 6kA Differential Circuit Breaker — Comprehensive Electrical Protection

NB1L-40 2P C16 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 offers enhanced safety and convenience. Its 30mA sensitivity provides crucial personnel protection, while the Type A characteristic ensures reliable tripping for AC and pulsating DC leakage currents, making it ideal for both residential and commercial applications.
