✅ CHINT NB1-63 C1 Miniature Circuit Breaker – 1P, 1A, C Curve, 6kA Breaking Capacity Description (English): This CHINT NB1-63 is a low voltage miniature circuit breaker (MCB) designed for reliable protection in residential, commercial, and light industrial installations. It is a 1P circuit breaker with 1 protected pole, a rated current of 1A, and a C tripping curve, making it suitable for resistive and inductive loads with moderate inrush currents. The MCB features a rated short-circuit breaking capacity of 6kA at 230V AC in accordance with EN/IEC 60898-1, and up to 50kA at 220–240V AC per EN/IEC 60947-2, offering robust protection against overloads and short circuits. The breaker is equipped with a toggle control mechanism, a trip indicator, and conforms to both industrial (EN/IEC 60947-2) and residential (EN/IEC 60898-1) standards. The VisiTrip indicator enables quick fault identification, while the VisiSafe strip ensures clear indication of safe disconnection. With a mechanical endurance of up to 20,000 cycles and electrical endurance up to 10,000 cycles, this device offers long operational life. It is DIN rail mountable, with a compact design of 18mm width, suitable for 2-pitch enclosures. Additional features include a rated insulation voltage of 500V, impulse withstand voltage of 6kV, IP20/IP40 protection in enclosure, and wide operating temperatures from -35°C to +70°C.
