RSS MV switchgear


The RSSw-24/630w switchgear is intended for application in container transformer stations with support provided inside and in all types of indoor stations.


The enclosure is made of aluzinc sheet, riveted and screwed, with the design facilitating access to the instruments, which translates into increased safety and intuitive work during installation and operation activities. The system of mechanical locks prevents misconnections. The distribution cubicle has three isolated sections, for the cable box, the disconnector and the secondary circuits.

KLS 24 and KLSF 24 UESA disconnecting switches are used in the distribution unit. NAL and NALF devices by ABB can be also used. The distribution cubicles are made in the arc protection standard.

The configuration and selection of additional equipment should be agreed with the representatives of the company.
