✅ CHINT NB1-63 C32 Miniature Circuit Breaker – 1P, 32A, C Curve, 6kA Breaking Capacity
Description (English):
This CHINT NB1-63 is a low voltage miniature circuit breaker (MCB) engineered for robust protection in residential, commercial, and light industrial electrical systems. Featuring 1 protected pole, a rated current of 32A, and a C tripping curve, it is ideal for circuits powering larger appliances, heavy sockets, and moderate motor loads.
It offers a short-circuit breaking capacity of 6kA at 230V AC according to EN/IEC 60898-1 and up to 50kA at 220–240V AC per EN/IEC 60947-2, providing dependable protection against overload and fault currents.
Equipped with a toggle switch, VisiTrip indicator for fault detection, and VisiSafe disconnection strip for secure maintenance visibility, the MCB meets both industrial and residential standards.
The device supports up to 20,000 mechanical operations and 10,000 electrical operations. With a compact 18mm width (2 DIN pitch), it fits easily into modular distribution panels.
Other specifications include 500V insulation voltage, 6kV impulse withstand voltage, IP20/IP40 enclosure protection, and an operating temperature range from -35°C to +70°C.
