NYKW3 series intelligent air circuit breaker

• NYKW3-1250 series intelligent air circuit breaker (hereinafter referred to as circuit breaker) has features of compact structure, small volume, high reliability and zero arcing, etc.. Rated insulation voltage of circuit breaker is 690V, applying to AC 50Hz, 400V rated working voltage and 200A-1250A rated current. It’s mainly used in distribution network to distribute electricity, protect circuit and power supply equipment from over-load, under-voltage, short circuit and single-phase grounding fault hazards.
• The circuit breaker is a three-dimensional arrangement, contact system of every phase is closed inside insulation base, forming a small independent chamber. These chambers constitute main circuit of circuit breaker.
• Technical performance of circuit breaker conforms to standards of GB14048.2 Low-Voltage Switch Equipment and Controlling Equipment Low-Voltage Circuit Breaker and IEC60947-2 Low-Voltage Switch Equipment and Controlling Equipment Secondary Low-Voltage Circuit Breaker.
