✅ CHINT NB1-63 C32 Miniature Circuit Breaker – 4P, 32A, C Curve, 6kA Breaking Capacity Description (English): The CHINT NB1-63 C32 is a four-pole miniature circuit breaker (MCB) designed for comprehensive protection in three-phase + neutral systems. With a rated current of 32A and a C tripping curve, this MCB is ideal for balanced electrical loads in residential, commercial, and light industrial settings — including HVAC panels, distribution boards, and motor circuits. It delivers a rated short-circuit breaking capacity of 6kA at 400V AC in compliance with EN/IEC 60898-1, and up to 50kA under EN/IEC 60947-2, ensuring reliable protection from overloads and short circuits across all four poles. The breaker is equipped with a toggle actuator, a VisiTrip indicator for quick fault detection, and a VisiSafe strip that confirms physical disconnection. Its compact 72mm width (4 DIN pitches) and DIN rail compatibility make it easy to install in modular distribution boards. The NB1-63 C32 supports 20,000 mechanical and 10,000 electrical operations. It also features a 500V insulation voltage, 6kV impulse withstand voltage, and IP20/IP40 enclosure protection for safe, long-lasting performance.
