✅ CHINT NB1-63 C16 Miniature Circuit Breaker – 2P, 16A, C Curve, 6kA Breaking Capacity Description (English): The CHINT NB1-63 C16 is a double-pole miniature circuit breaker (MCB) engineered for enhanced protection in residential, commercial, and light industrial installations. With 2 protected poles and a rated current of 16A, it is suitable for two-phase power circuits, providing coordinated disconnection in case of faults. It features a C tripping curve, making it ideal for mixed-load applications with moderate inrush currents. The MCB delivers a 6kA breaking capacity at 230/400V AC per EN/IEC 60898-1 and up to 50kA per EN/IEC 60947-2, ensuring reliable protection against both overload and short circuit faults. The unit includes a toggle mechanism for manual control, VisiTrip fault indication, and VisiSafe disconnection verification, promoting operational safety and ease of maintenance. It complies fully with IEC 60898-1 and 60947-2 standards. With a compact 36mm profile (2-pole, 2-pitch), the device is DIN rail mountable and supports flexible wiring. It offers long service life with 20,000 mechanical operations and 10,000 electrical operations. Additional technical details include a 500V insulation rating, 6kV impulse withstand voltage, IP20/IP40 protection in panel enclosures, and an operating temperature range from -35°C to +70°C.
