MV AIR INSULATED SWITCHBOARD - BY ABB
UniSec SDC (Switch Disconnector Cubicle)
Units available in the 375 mm, 500 mm and 750 mm widths. The switch-disconnector unit with cable is mainly used as an incoming, ring or branch unit. The basic unit is equipped with a 3-position switch-disconnector. The 3-position switch- disconnector can be in one of three positions: “closed”, “open” or “earthed”, therefore preventing incorrect operations. Access to the cable compartment is possible in the “earthed” position.
Inspection of cable connections and fault indicators, when used, is easily carried out through the front-door window.
