The Chint NB1-63H is a two-pole miniature circuit breaker rated at 63A with a Type B tripping characteristic, providing overcurrent and short-circuit protection for final and sub-main circuits. It offers a rated breaking capacity of 10kA to IEC/EN 60898-1 and operates at 230/400V AC, 50/60Hz. The breaker mounts on 35mm DIN rail and occupies two modules (36mm overall, 18mm per pole), with screw terminals accepting conductors up to 25mm² at a tightening torque of 2.0Nm. A Type B curve trips at three to five times rated current, suiting resistive and lightly inductive loads. The device has a rated impulse withstand voltage of 4kV and an IP20 front. Rated for operation from −35°C to +70°C.
