CHINT NB1L 2P C20 30mA 10kA Differential Circuit Breaker

NB1L 2P C20 30mA A 10kA Differential Circuit Breaker — Comprehensive Electrical Safety

NB1L 2P C20 30mA A 10kA is a compact, two-pole Residual Current Circuit Breaker with Overcurrent protection (RCBO) from CHINT. This device combines the functions of a miniature circuit breaker and a residual current device (RCD) in a single unit, providing comprehensive protection against short circuits, overloads, and electrical leakage. Its 30mA sensitivity and Type A characteristic ensure protection against both sinusoidal alternating and pulsating DC leakage currents, maximizing personal safety. The high breaking capacity of 10kA makes it suitable for installations with potentially high fault currents.
