NKW1 series universal circuit breaker (also called Air Circuit Breaker/ACB) is suitable for electrical energy distribution and protection of circuit in the distribution network of AC 50Hz / 60Hz, rated current 400-6300A, rated insulation voltage AC1000V, rated working voltage AC400V, AC690V. It can protect electrical equipments from the hazards of overload, undervoltage, short circuit, single-phase grounding and other faults. At the same time, it has isolation function. The variety of protection functions of the circuit breaker can achieve high-precision selective protection, avoid unnecessary power outages, and improve power supply reliability and safety. NPK1-2000, 3000 (GH) live replaceable controller circuit breaker is a new structure circuit breaker newly developed by our company that can quickly replace the controller without opening the cabinet door or cutting the main circuit. The rated current is 400-3200A, which can meet the requirements of zero power outage. It is the first product at home and abroad and has a number of invention patents and utility model patent.
