CHINT NA1-1000X/2000X 3P 1000A 220V Fixed/Drawout ACB

Chint NA1 series air circuit breaker is suitable for AC 50Hz/60Hz circuits with rated operational voltage 400V and 690V,
and rated current up to 6300A. It is mainly used to distribute electric energy and to protect circuits and electrical equipment
against overload, under-voltage, short-circuit, and single-phase earthing fault. Typical applications include power stations,
factories, mines, and modern high-rise building distribution systems.

• High current application: suitable for low-voltage distribution systems with rated current up to 6300A.
• Voltage options: suitable for 400V and 690V AC systems.
• Protection capability: used for overload, under-voltage, short-circuit, and single-phase earthing fault protection.
• Protection type: LSI.
• Breaking capacity range: 25kA – 100kA.
• Standard reference: IEC/EN 60947-2.
