Description
The blade moves in the plane of the insulators, so the phase-to-phase distance is minimal. In the SLOB the blade is driven by rotating an insulator, a variant designed for high short-circuit currents. The SLOB comes in single and double column versions for outdoor use. The SHD and SLOB are the base for the LBS and VSD load-break switches.

Questions and answers
What voltage range do the SHD and SLOB cover?
The SHD works at 17.5–72.5 kV and the SLOB at 72.5–550 kV.
Why use a vertical break?
The blade moves in the plane of the insulators and the phase-to-phase distance can be made minimal, which saves space in outdoor switchgear.
What short-circuit withstand does the disconnector have?
Short-time withstand current up to 75 kA for 3 s, rated current up to 6300 A.
