✅ CHINT NB1-63H C10 Miniature Circuit Breaker – 2P, 10A, C Curve, 10kA Breaking Capacity Description (English): The CHINT NB1-63H C10 is a double-pole miniature circuit breaker (MCB) designed to deliver safe and reliable protection for dual-phase circuits in residential, commercial, and light industrial systems. With a rated current of 10A and a C curve tripping profile, it is well-suited for lighting circuits, small loads, and socket outlets with moderate inrush currents. This MCB offers a high breaking capacity of 10kA at 230V AC, ensuring strong protection against overloads and short circuits. It complies with EN/IEC 60898-1 and EN/IEC 60947-2 standards for both residential and industrial-grade performance. Equipped with a toggle switch for manual operation, a VisiTrip indicator for rapid fault detection, and a VisiSafe strip for visual disconnection confirmation, the NB1-63H C10 ensures operational safety. Its 36mm width fits DIN rail systems (4-pitch) and allows easy installation in compact panels. It features a rated insulation voltage of 500V, impulse withstand voltage of 6kV, IP20/IP40 protection rating, and reliable operation in environments ranging from -35°C to +70°C. With a mechanical endurance of 20,000 cycles and an electrical life of 10,000 operations, the breaker guarantees long-term durability.
