✅ CHINT NB1-63H C6 Miniature Circuit Breaker – 1P, 6A, C Curve, 10kA Breaking Capacity Description (English): This CHINT NB1-63H is a high-performance miniature circuit breaker (MCB) designed for reliable protection in residential, commercial, and control applications. It is a 1P breaker with 1 protected pole, a rated current of 6A, and a C tripping curve, making it suitable for circuits with lighting, small motors, or mixed resistive/inductive loads. With a short-circuit breaking capacity of 10kA at 230V AC, the NB1-63H C6 ensures excellent fault interruption capability. It complies with both EN/IEC 60898-1 and EN/IEC 60947-2 standards and operates at a frequency of 50/60Hz. The breaker features a toggle control switch, a VisiTrip indicator for easy fault identification, and a VisiSafe strip that confirms complete physical disconnection. Its compact 18mm (2-pitch) width supports easy mounting on DIN rails in modular distribution panels. Built for durability, it offers mechanical endurance of 20,000 cycles and electrical endurance of 10,000 cycles. It also provides an insulation voltage of 500V, impulse withstand voltage of 6kV, and IP20/IP40 protection when used in an enclosure.
