Environmental disconnect switch BHEDSG-12/630/3


This is a environmental disconnect switch for use with environmentally friendly circuit breaker switches, sealed in a dry gas filled stainless steel enclosure. The three-position switch has three positions of closing, isolating and earthing, adopting rotary operating mechanism, reliable positioning of each position and visualisation of the break. The vacuum circuit breaker mechanism adopts modular design, with a small number of mechanism parts, compact structure, low operating power and stable performance. There is a perfect mechanical interlocking between the disconnecting switch and the vacuum circuit breaker to ensure the safety of operation.
