Product Description
Gas-insulated indoor switch disconnector
The UN-LBS is a gas-insulated switch disconnector for medium voltage switchgear within secondary distribution networks. There are several advantages that make the UN-LBS concept suitable for many different applications. For instance the compact size and the lightweight construction of the switch disconnector are significant features for smart integration.
There are two types of operating mechanisms: the single spring device and the double spring device. Motor operation can be added to both types of operating mechanisms.
