Product Description

HLK-3S-40.5 Outdoor Pole Mounted (permanent magnet) Vacuum Circuit Breaker

Product detail
The HLK-3S-40.5 series of outdoor pole mounting permanent magnet vacuum circuit breakers are a new generation of column-mounted intelligence developed by our company, which integrates advanced technology at home and abroad, takes advantage of the strengths of others, adopts new design concepts and newly developed Vacuum circuit breaker. This product is used as a switch for the main transformer outgoing line of a 35kV substation, and can also be used as a pole switch of the distribution network. It can be combined with various control units produced by our company to easily achieve control, protection, satellite measurement, and communication. It is the first choice for network automation and miniaturization.
