1.High dieletric performance,protective capability
2.Power isolating switch is of flexible structure modulariczed design
HUH1 series isolating switch is mainly applied in the circuits with voltage up to 690V, rated frequency of 50Hz, and rated current up to 3200A for making and breaking circuit or isolating functions in power distribution circuit. It is classified into 11 specifications from 125A to 1600A viz. basic types of modularization design. It has 3 poles or 4 poles (3 poles plus a neutral pole), which is applied for making and breaking or electric isolation to the current above 1000A. The product complies with the standards of IEC60947-3 and GB14048.3.
