The horizontal double break disconnectors consists of three poles. Each pole consists of a frame, two supporting insulators at each end and one rotating insulator in the centre, on which the main blade is mounted. The types TFD and TFX are for outdoor, the type TID for indoor use.

They can be equipped with insulators in accordance with DIN, IEC or other specifications.

The double break disconnectors are operated single-pole or three-pole by means of a motor or manual operated drive mechanism inside an IP54 housing, with torques up 850Nm and including up to 10 auxiliary contacts for position indication.

Optional earthing switches can be build-on to the horizontal double break disconnector to the right hand side and/or to the left hand side.

All disconnectors are designed and tested in accordance with latest IEC specifications.
