NLDW1-1600 series universal circuit breakers (hereinafter referred to as circuit breakers) are suitable for AC 50Hz distribution networks with rated voltage of AC400V/690V and below, and rated current ranging from 200A to 1600A. They are mainly used to distribute electrical energy, and protect circuits and power equipment from overload, undervoltage, short circuit,single-phase grounding and other faults. Under normal conditions, it can also be used for infrequent switching of lines. The circuit breaker has intelligent protection function, precise selective protection, can improve power supply reliability and avoid unnecessary power outages. At the same time, it has an open communication interface and can be used for "four remotes" to meet the requirements of the control center and automation system.
