✅ CHINT NB1-63 C10 Miniature Circuit Breaker – 2P, 10A, C Curve, 6kA Breaking Capacity Description (English): This CHINT NB1-63 is a double-pole miniature circuit breaker (MCB) designed for effective protection in residential, commercial, and light industrial applications. It features 2 protected poles, a rated current of 10A, and a C tripping curve, making it ideal for single-phase 2-wire circuits and balanced load applications. It provides a short-circuit breaking capacity of 6kA at 230/400V AC in accordance with EN/IEC 60898-1, and up to 50kA under EN/IEC 60947-2, offering robust protection against both overload and fault currents across both poles simultaneously. Equipped with a toggle operation mechanism, VisiTrip fault indication, and VisiSafe isolation confirmation, it ensures easy identification of faults and safe downstream maintenance. The breaker complies with both residential and industrial standards. With a compact 36mm width (2 DIN pitches), it is DIN rail mountable and suitable for modular panels. It also features a long operating life with 20,000 mechanical operations and 10,000 electrical operations. Additional features include 500V insulation voltage, 6kV impulse withstand voltage, IP20/IP40 protection (when enclosed), and a wide operating temperature range from -35°C to +70°C.
