All control and indicating devices are located on the front of the circuit breaker unit. These include manual close/open knob, manual charging slot, position switch, operation counter, close/open indicator, spring charged and discharged indicator.

The circuit breaker is mounted on truck for horizontal withdrawal and isolation. Both the ‘service’ and ‘isolate/test’ positions are within the compartment.

Safety shutters are provided within the circuit breaker compartment. These automatic safety shutters cover the busbars and feeder spouts when the circuit breaker is at the ‘isolate/test’ position. They can be padlocked in the closed position if so desired and kept open for testing and maintenance purposes by means of manually operated catches, which in turn are self cancelling when the circuit breaker is returned to the unit.

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.
