✅ CHINT NB1-63H C25 Miniature Circuit Breaker – 2P, 25A, C Curve, 10kA Breaking Capacity Description (English): The CHINT NB1-63H C25 is a high-performance 2-pole miniature circuit breaker (MCB) designed to protect dual-phase electrical circuits in residential, commercial, and light industrial systems. With a rated current of 25A and a C curve tripping profile, it is ideal for moderate-to-high load applications, including HVAC units, small motors, and control panels. This MCB offers a high short-circuit breaking capacity of 10kA at 230V AC, providing strong protection against both overloads and short circuits. It complies with EN/IEC 60898-1 and EN/IEC 60947-2 standards, ensuring versatility across a wide range of installations. The NB1-63H C25 features a toggle-type manual actuator, a VisiTrip indicator for fast fault recognition, and a VisiSafe disconnection strip for clear visual confirmation of open contacts. The device fits standard DIN rail systems (36mm width, 4-pitch), enabling compact and fast installation. With a 500V rated insulation voltage and 6kV impulse withstand capability, it operates reliably between -35°C and +70°C. Its long life span includes 20,000 mechanical cycles and 10,000 electrical operations.
