✅ CHINT NB1-63 C32 Miniature Circuit Breaker – 2P, 32A, C Curve, 6kA Breaking Capacity Description (English): The CHINT NB1-63 C32 is a double-pole miniature circuit breaker (MCB) engineered to provide robust protection for dual-phase circuits in residential, commercial, and light industrial settings. With a rated current of 32A and a C tripping curve, it is suitable for higher-capacity loads such as HVAC systems, motor-driven equipment, and high-demand socket circuits. This breaker offers a 6kA short-circuit breaking capacity at 230/400V AC in compliance with EN/IEC 60898-1, and up to 50kA per EN/IEC 60947-2, ensuring safe and effective protection from overloads and short circuits on both poles simultaneously. Equipped with a manual toggle switch, VisiTrip fault indicator, and VisiSafe isolation strip, it allows for fast fault detection and safe maintenance procedures. The compact 36mm DIN rail-mounted design makes it suitable for space-limited installations. Its mechanical endurance reaches 20,000 cycles and electrical endurance up to 10,000 cycles, making it reliable for long-term use. It also features a rated insulation voltage of 500V, impulse withstand voltage of 6kV, and IP20/IP40 protection when mounted inside enclosures.
