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.

Vacuum Circuit-Breaker (VCB) It is designed to accomodate high-performance vacuum circuit breaker (VCB) which has been designed, manufactured and tested in accordance with IEC 56 and BS 5311.
The switchgear itself conforms to IEC 60298 and BS 5227, and the all primary components employed therein are in accordance with the relevant IEC and/ or BS Standars. The modern production process has been introduced for the manufacture of main components, primarily in sheet-metal forming and gas-tight tank, the technique of gas tightness and jointing frameworks,surface protection and so on.
SF6 gas insulation used in conjunction with vacuum circuit-breaker (VCB) has set new standard with respect to:
Operational realiability and availability Reduced maintenance work Safety for operators Free from environmental pulution Reduced dimensions and less space requirements Capability of current interuption with zero gas pressure (at atmospheric pres sure) Motorised Busbar Live Transfer Discon nectors are provided for double Busbar switchgears

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.
