Scope of Application
NLW1O series Intelligent Universal Air Circuit Breakers (hereinafter referred to as breaker) is suitable for distribution systems with 50Hz, rated voltage 400V/690V, rated current 200A-1600A. It can distribute power and protect circuit and power device, prevent from danger of overload, under voltage, short circuit, single phase grounding, etc.. The 630A and below breaker can be used to operate motor directly, for its infrequently ON/OFF.
This breaker has feature: compact, intelligent and with multi protection. It can increase the reliability of the power supply, avoid unnecessary power off by precise selective protection. Meanwhile, it is with multi opening communication interface, which is convenient for electricity distribution automation in control center and automation system.
This breaker also has isolating function. It can be used as isolator, while without intelligent controller and sensors. The symbol is
