✅ CHINT NB1-63H C16 Miniature Circuit Breaker – 1P, 16A, C Curve, 10kA Breaking Capacity Description (English): This CHINT NB1-63H miniature circuit breaker (MCB) is designed for robust and precise protection in residential, commercial, and light industrial electrical installations. It features one protected pole (1P), a rated current of 16A, and a C tripping curve suitable for mixed loads including lighting, outlets, and motor-driven equipment with moderate inrush currents. Engineered for performance and reliability, the NB1-63H C16 offers a high short-circuit breaking capacity of 10kA at 230V AC, tested and certified in accordance with EN/IEC 60898-1. It also complies with EN/IEC 60947-2 standards for industrial-grade operation. The breaker incorporates a toggle actuator, VisiTrip indicator for quick fault detection, and a VisiSafe mechanical indicator that confirms full contact separation. Its slim 18mm body fits seamlessly on 2-pitch DIN rails in modern distribution panels. Designed for long operational life, it provides up to 20,000 mechanical cycles and 10,000 electrical cycles. The device supports 500V insulation voltage, 6kV impulse withstand voltage, and IP20/IP40 protection when installed in an enclosure.
