✅ CHINT NB1-63 C16 Miniature Circuit Breaker – 1P, 16A, C Curve, 6kA Breaking Capacity Description (English): This CHINT NB1-63 is a low voltage miniature circuit breaker (MCB) designed for dependable protection in residential, commercial, and light industrial applications. It is a 1P circuit breaker with 1 protected pole, a rated current of 16A, and a C tripping curve, making it ideal for mixed loads such as lighting circuits, small motors, and socket outlets. The MCB features a rated short-circuit breaking capacity of 6kA at 230V AC according to EN/IEC 60898-1, and up to 50kA at 220–240V AC under EN/IEC 60947-2 standards, ensuring strong protection against overloads and short-circuit faults. The device includes a toggle control mechanism and a trip indication feature for easy fault identification. It complies with both industrial (EN/IEC 60947-2) and residential (EN/IEC 60898-1) norms. The VisiTrip and VisiSafe technologies enhance operational safety and maintenance efficiency. With a robust mechanical life of up to 20,000 cycles and an electrical life of 10,000 cycles, this circuit breaker offers long-term reliability. It mounts easily on standard DIN rails and fits compactly into panels with its 18mm width (2-pitch) form factor. Other features include a 500V rated insulation voltage, 6kV impulse withstand voltage, IP20/IP40 enclosure protection, and wide ambient operating temperatures from -35°C to +70°C.
