Chint NA1-1000X-800M/3P

The Chint NA1-1000X-800M/3P is a robust low-voltage air circuit breaker (ACB) designed for industrial and commercial power distribution systems. Engineered for reliability and safety, this ACB delivers dependable protection and control for three-phase electrical circuits up to 800 A rated current.
Built to international standards (IEC/EN 60947-2), the NA1 series protects electrical installations against overload, short-circuit, under-voltage faults, and earth faults. Its intelligent protection functions help minimize downtime and prevent equipment damage, making it ideal for use in power stations, factories, large buildings, and modern automated systems.
The “1000X” frame size provides a compact yet powerful solution, offering a strong breaking capacity and enhanced electrical life in demanding environments. The 3-pole (3P) configuration supports three-phase AC systems, and the device can be supplied in fixed or draw-out mounting formats, with manual or motorized operation options depending on installation requirements.
