NB1L-40 2P C25 30mA A 6kA Differential Circuit Breaker — Comprehensive Electrical Protection
NB1L-40 2P C25 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 ensures rapid disconnection in the event of an earth fault, while the Type A characteristic detects both AC and pulsating DC leakage currents, enhancing safety in modern electrical installations. Ideal for residential and commercial applications.
