CHINT NB1L 2P C40 30mA 10kA Differential Circuit Breaker (54mm)

NB1L 2P C40 30mA A 10kA Differential Circuit Breaker — Comprehensive Electrical Safety

NB1L 2P C40 30mA A 10kA is a compact, two-pole Residual Current Circuit Breaker with Overcurrent protection (RCBO) from CHINT. This device provides comprehensive protection against short circuits, overloads, and earth leakage currents. Combining the functions of a miniature circuit breaker (MCB) and a Residual Current Device (RCD), it offers enhanced safety with 30mA sensitivity and Type A protection, responding to both sinusoidal AC and pulsating DC leakage currents. Its 10kA breaking capacity makes it suitable for demanding electrical systems.
