✅ CHINT NB1-63 C25 Miniature Circuit Breaker – 1P, 25A, C Curve, 6kA Breaking Capacity Description (English): This CHINT NB1-63 is a low voltage miniature circuit breaker (MCB) engineered for safe and efficient protection in residential, commercial, and light industrial circuits. It is a 1P device with one protected pole, a rated current of 25A, and a C tripping curve, making it ideal for higher-demand circuits such as power outlets, air conditioners, and machine controls with moderate inrush current. The MCB delivers a short-circuit breaking capacity of 6kA at 230V AC in accordance with EN/IEC 60898-1, and up to 50kA at 220–240V AC according to EN/IEC 60947-2, ensuring durable protection against both overloads and short-circuit faults. It includes a toggle actuator, trip indication via VisiTrip, and a safety disconnection indicator via VisiSafe. Fully compliant with both residential and industrial standards, this breaker allows easy identification and safer maintenance operations. With up to 20,000 mechanical operations and 10,000 electrical operations, the NB1-63 ensures long-lasting reliability. It mounts on standard DIN rails and occupies just 18mm of width (2 pitch), optimizing space in electrical panels. Other technical features include a 500V insulation voltage, 6kV impulse withstand voltage, IP20/IP40 protection in enclosure, and an operating temperature range from -35°C to +70°C.
