COMPONENTS
Roof Switch for rolling stock
Type RS
General informations
The RS is an off-load switch, electrically or electro-pneumatically
operated, and designed mainly to be installed outdoors on the
roof of electric traction vehicles.
The RS is available in three main executions: change-over switch,
disconnect switch, as well as disconnect and earthing switch.
It is suitable for single-voltage as well as for multi-voltage
vehicles, covering all the usual line voltages (1.5 kVdc;
3 kVdc; 15 kVac and 25 kVac) as well as the different
vehicle’s currents rated from 1000 A to 4000 A.
Applications
Roof switch for locomotives, trains and EMUs running on ac and/or dc networks.
Application C
Change-over switch
Application D
Disconnect switch
Application E
Disconnect and earthing switch

Electro-pneumatic operation (RS..10, RS..20, RS..30)
The electro-pneumatic drive fits in the same volume as the
electric drive.
The customer’s air circuit is connected directly into the G1/4”
L-connection of the cylinder valve, by means of a quick release
air connection (to be ordered separately - refer to page 7).
High voltage contact - Ice protection
Only for RS..10, RS..20, RS..30
Assembled on the top of the fixed contacts, this protection limits the
impact of icing conditions on the RS functionality.
Note: for harsh environmental conditions contact Sécheron to
evaluate the most appropriate solution.
Roof execution
Special executions to install the complete RS on the roof (without roof opening) are available for the electric version upon request.
