Single pole disconnector for neutral point disconnection is to be found in two basic designs, EFG and GDSG.

EFG is a simple variant and is edified, like our fuse disconnector L33, with a disconnector blade that is operated from the ground, with an isolated stick.

GDSG-E is edified like our over line disconnector GDS. It’s delivered with assembling parts combined both for poles and wall, and with an operation rod. GDSG-ES can be delivered with a auxiliary contact.
Disconnector GDSG can even be delivered with a motor operator, alternative even as load break disconnector.
