✅ CHINT NB1-63H C16 Miniature Circuit Breaker – 3P, 16A, C Curve, 10kA Breaking Capacity Description (English): The CHINT NB1-63H C16 is a 3-pole miniature circuit breaker (MCB) engineered for reliable protection of three-phase systems across residential, commercial, and industrial sectors. With a rated current of 16A and a C tripping curve, it is ideal for lighting circuits, small motor loads, and general-purpose equipment with moderate inrush current. The device offers a high short-circuit breaking capacity of 10kA at 400V AC and ensures consistent performance against overloads and short circuits. It meets global standards EN/IEC 60898-1 and EN/IEC 60947-2. This MCB features a toggle control handle, a VisiTrip indicator for instant fault identification, and a VisiSafe strip to confirm safe physical disconnection. Designed for modular panel installations, it fits DIN rails with a 6-pitch (54mm) width. With an insulation voltage rating of 500V and impulse withstand voltage of 6kV, the NB1-63H C16 supports harsh operating environments from -35°C to +70°C. It also offers excellent durability with 20,000 mechanical and 10,000 electrical cycles.
