Circuit breaker switchboard XGN2-12 series

ACfor industrial applications

This series of product is suitable for indoor single busbar of three phase AC 50Hz, rated voltage 3.6 ~ 12kV, main busbar rated current up to 4000A, and it can be a derivative single busbar with bypass power system. For the moment, the technical parameters are in the leading level in domestic. The product is a metal enclosed box-type structure, with high intensity of enclosure. The inside of the device is separated into circuit breaker compartment, busbar compartment, cable compartment, relay compartment.Each compartment is provided with a separate nature ventilation and dedicated pressure relief passage to ensure the safetey of personnel and equipment. The product adopts rotary disconnector, double break point dynamic contact grounding in disconnect position, that is it will form “metal isolation” between live conductors and the isolated conductors to ensure the safety of maintenance personnel. The insulating medium of air can meet the full conditions required,with high reliability during operation. The interlocking mechanism between the main circuit breaker, disconnector, earthing switch and door plate, adopts mandatory mechanical locking method for easy operation and maintenance, which fully meets the stipulated “Five prevention” locking functions.
