Switchgear Low voltage

The HNS series has absorbed the design structure merits of domestic and abroad Inteligent AC low voltage power switch boxes, like GCK, GCS, MNS. With the independent development ,our product take the leading technical level of the same profession in domestic and abroad,it is suitable to rated voltage 400v/690v and below,rated power 50Hz/60Hz, the main bus bar(horizontal bus bar) at 6300A,the power distribution bus bar(vertical bus) to 2000A and the following series HNS Inteligent AC low voltage power switch box.
