✅ CHINT NB1-63H C10 Miniature Circuit Breaker – 3P, 10A, C Curve, 10kA Breaking Capacity Description (English): The CHINT NB1-63H C10 is a three-pole miniature circuit breaker (MCB) designed to provide dependable protection for three-phase electrical systems. With a rated current of 10A and a C curve tripping characteristic, it is ideal for applications with moderate inrush current, such as lighting circuits, distribution panels, and small machinery. Engineered to deliver a high short-circuit breaking capacity of 10kA at 400V AC, this MCB ensures effective protection against overloads and short circuits in commercial, residential, and industrial environments. It complies with EN/IEC 60898-1 and EN/IEC 60947-2 safety standards. The NB1-63H C10 features a toggle switch for manual operation, a VisiTrip indicator for fast fault identification, and a VisiSafe disconnection strip for enhanced safety. With a compact 54mm width (6-pitch), it is easily mountable on DIN rails in standard panel boards. The device supports a 500V insulation voltage, 6kV impulse withstand voltage, and is rated for long operating life with 20,000 mechanical cycles and 10,000 electrical operations.
