Chint NB1L-63 miniature circuit breaker 1-pole B6/10/13/16/20/25/32/40A 6kA

CHINT NB1L-63 1-Pole B Curve Circuit Breaker 6–40 A, 6 kA

The CHINT NB1L-63 1-pole circuit breaker with B tripping characteristic is designed for single-phase electrical circuits with low to moderate inrush currents. It provides reliable protection against overload and short circuit and is suitable for standard building, commercial and technical electrical installations.

The available rated currents of 6, 10, 13, 16, 20, 25, 32 and 40 A make this version particularly flexible for a wide range of single-phase applications. The 6 kA breaking capacity supports reliable protection in standard low-voltage installations.
