These are the busbar coupling cells that are designed with load separator in applications of which rated current is up to 630 A and of which short circuit strength is up to 20 kA, or with separator when these values are higher.

Load separator might be used on these cells, whereas optionally 3 polar, 3 position (open- closed-grounding rod) SF6 gas insulated or revolving separator up to 1250 A rated current and 25 kA short circuit current might be used.

Load separator busbar segmenting cells are used for coupling of two busbars through manual switching without secondary protection.
