✅ CHINT NB1-63H C16 Miniature Circuit Breaker – 2P, 16A, C Curve, 10kA Breaking Capacity Description (English): The CHINT NB1-63H C16 is a 2-pole miniature circuit breaker (MCB) engineered to protect dual-phase circuits from overloads and short circuits in residential, commercial, and light industrial applications. With a rated current of 16A and a C curve tripping characteristic, it is ideal for socket outlets, lighting systems, and control panels with medium inrush currents. Offering a high short-circuit breaking capacity of 10kA at 230V AC, the NB1-63H C16 ensures safe and rapid disconnection under fault conditions. It meets both EN/IEC 60898-1 and EN/IEC 60947-2 standards, combining residential compliance with industrial-grade performance. The device features a manual toggle actuator, a VisiTrip indicator for easy fault location, and a VisiSafe strip that provides visual confirmation of physical disconnection. With a compact 36mm width (4-pitch), it supports DIN rail mounting for efficient panel integration. It operates reliably at temperatures from -35°C to +70°C, with an insulation voltage of 500V and an impulse withstand voltage of 6kV. It delivers a long service life, rated for 20,000 mechanical operations and 10,000 electrical cycles.
