The ROSSS consists of three switch units, whereas the ROKSS is a switch-fuse unit, combined with two switch units. In both units the switch and/ or switch fuses are mounted side by side in coon welded steel tanks. On both units, the tank is fitted with four hinged access covers. The left-hand covers the ROKSS gives access to the fuses while the other covers on both the ROSSS and ROKSS permit contact or cable testing on the circuit switches and switch-fuse where fitted. In addition to the normal non-extinsible and extensible ROKSS units a direct connected tee-off switch-fuse version is available for mounting directly onto a transformer. The flange lines up with a standard transformer flange.
