✅ CHINT NB1-63 C10 Miniature Circuit Breaker – 4P, 10A, C Curve, 6kA Breaking Capacity Description (English): The CHINT NB1-63 C10 is a four-pole miniature circuit breaker (MCB) engineered to provide full-phase protection in three-phase + neutral systems. With a rated current of 10A and a C tripping curve, it is ideal for small commercial loads and balanced circuits requiring reliable overload and short circuit protection across all four poles. It offers a rated short-circuit breaking capacity of 6kA at 400V AC in accordance with EN/IEC 60898-1 and up to 50kA per EN/IEC 60947-2, ensuring robust protection and safe disconnection under fault conditions. Equipped with a toggle actuator, VisiTrip indicator for fast fault detection, and a VisiSafe strip for physical disconnection verification, the NB1-63 C10 is DIN rail mountable and 72mm wide (4 pitch), ensuring easy integration in distribution boards. It also features a 500V insulation voltage, 6kV impulse withstand voltage, and is IP20/IP40 rated when enclosed. With mechanical durability of 20,000 operations and electrical endurance of 10,000 cycles, it provides long-lasting, consistent protection.
