We tailor our solutions to you
R&S produces horizontal, vertical and pantograph disconnectors, as well as earthing switches and motor drives. Depending on the application in question and customer requests, we offer single-phase, double-phase and three-phase versions. Our flexible Engineering and Design Department will find the perfect customised solution for you.

Horizontal disconnector
- Used to ensure that an electrical circuit is completely de-energised for servicing or maintenance- Single-pole, double-pole or three-pole
- Each pole consists of a frame and two supporting insulators that the main blade is mounted on

Pantograph disconnectors
- Used to ensure that an electrical circuit is completely de-energised for servicing- Minimal space requirements
- Single-pole, double-pole or three-pole
- Each pole consists of one support insulator, one rotating insulator, the pantograph mechanism and a counter contact

Vertical disconnectors
- Used to ensure that an electrical circuit is completely de-energised for servicing or maintenance- Single-pole, double-pole or three-pole
- Each pole consists of a frame, one rotating insulator and two support insulators that the main blade is mounted on

Earthing switches
- Used to earth the residual charge after the line is disconnected from the source- Single-pole and three-pole versions available

Motor drives
- Local, remote and manual control- Anti-corrosion heating
- Mounted on special tables or directly on the frame
- Control voltage: 230 V AC, 220 V DC, 110 V DC, 60 V DC
- Motor voltage: 400 V AC, 230 V AC, 110 V DC, 220 V DC
- On / off / intermediate / advanced signalling
