✅ CHINT NB1-63 C32 Miniature Circuit Breaker – 3P, 32A, C Curve, 6kA Breaking Capacity Description (English): The CHINT NB1-63 C32 is a robust triple-pole miniature circuit breaker (MCB) designed to protect three-phase circuits in residential, commercial, and light industrial settings. With a rated current of 32A and a C tripping curve, it is ideal for medium to heavy loads such as HVAC units, lighting banks, industrial plugs, and machine panels. It features a short-circuit breaking capacity of 6kA at 400V AC in compliance with EN/IEC 60898-1 and up to 50kA according to EN/IEC 60947-2, providing dependable protection against overloads and faults across all three poles. The breaker includes a manual toggle switch, a VisiTrip indicator for immediate fault detection, and a VisiSafe strip for visual confirmation of isolation. Its compact 54mm width (3 DIN pitches) makes it ideal for installation in modular electrical panels. Built for long service life, it supports up to 20,000 mechanical operations and 10,000 electrical operations. The NB1-63 C32 also offers 500V insulation voltage, 6kV impulse withstand voltage, and IP20/IP40 protection in enclosure-mounted applications.
