MV AIR INSULATED SWITCHBOARD - BY ABB
UniSec DRC (Direct Incoming Unit with Measurement and Busbar Earthing)
Unit available in the 375 mm and 500 mm widths.
To connect cables directly to the busbars, a direct riser unit is available. The lower front door is fixed and can only be opened with a tool. The door has a window for inspection. The earthing switch with full making capacity can be installed in the 500 mm unit. It can be used for earthing the switchgear busbars or the incoming line cable.
The panel can also be fitted with current transformers, combi sensors or voltage transformers. The unit is also available in the version without cable output for measurements (voltage) and busbar earthing.
