✅ CHINT NB1-63H C32 Miniature Circuit Breaker – 1P, 32A, C Curve, 10kA Breaking Capacity
Description (English):
The CHINT NB1-63H C32 is a single-pole miniature circuit breaker (MCB) engineered to provide advanced protection for circuits in residential, commercial, and light industrial applications. With a rated current of 32A and a C curve tripping characteristic, it is ideal for circuits supplying larger loads such as socket banks, air conditioners, and industrial control equipment.
This MCB features a high short-circuit breaking capacity of 10kA at 230V AC in compliance with EN/IEC 60898-1, and it also meets the industrial-grade standard EN/IEC 60947-2 for performance and safety.
The device is equipped with a toggle control switch for manual operation, a VisiTrip indicator for immediate fault detection, and a VisiSafe indicator to confirm full physical isolation. The compact 18mm design fits on 2-pitch DIN rails, allowing quick integration into modular panels.
Additional technical features include an insulation voltage of 500V, impulse withstand voltage of 6kV, and ingress protection rating of IP20/IP40 when installed in an enclosure. It supports 20,000 mechanical operations and 10,000 electrical operations, and functions reliably between -35°C and +70°C.
