Product Description

The JGGY’s experience extends over 35 years in SF6 technology for Medium Voltage switchgear. This gives you the advantage of unique experience, that of a world leader, with over 2,700,000 SF6 Medium Voltage units installed throughout the world. Putting this experience at your service and remaining attentive to your requirements is the spirit of active partnership that we want to develop in offering you the LBSkit.

LBSkit is a product to let you develop harmonized functions equipped with SF6 breaking technology switchgear. These functions allow you to produce all your Medium Voltage substation requirements up to 36kV.The result of in-depth analysis of your requirements, both now and in the future, LBSkit means that you can take advantage of all the features of both a modern and proven technology.

LBSkit: a product designed with control and monitoring in mind

LBSkit is perfectly adapted to control and monitoring applications. Motorised, option available, LBSkit combines with remote control interface. You, therefore, benefit from a ready-to connect unit that is easy to incorporate providing guaranteed operation.

LBSkit: a product with adapted fuse-switch protection

With the LBSkit, Schneider Electric proposes components for MV protections with fuses. Fusarc CF fuse range is an excellent solution to protect various types devices such as MV transformers, motors, capacitors, public and industrial distribution networks.
