✅ CHINT NB1-63H C10 Miniature Circuit Breaker – 4P, 10A, C Curve, 10kA Breaking Capacity Description (English): The CHINT NB1-63H C10 is a four-pole miniature circuit breaker (MCB) built for safe and dependable protection of three-phase systems with neutral. Rated at 10A with a C curve tripping characteristic, it is suitable for mixed resistive and inductive loads such as lighting circuits, small motors, and socket outlets in both commercial and industrial installations. With a 10kA short-circuit breaking capacity at 400V AC, this breaker provides strong protection against overloads and faults. It complies with EN/IEC 60898-1 and EN/IEC 60947-2 standards for residential and industrial applications. The breaker includes a manual toggle actuator, a VisiTrip indicator for fault detection, and a VisiSafe strip for secure disconnection confirmation. It has a compact 72mm (8-pitch) width for easy DIN rail mounting. Additional specs include 500V insulation voltage, 6kV impulse withstand capability, and endurance of 20,000 mechanical and 10,000 electrical cycles, with a wide operating range from -35°C to +70°C.
