FunctionsSIRCOVER products are manuallyoperated multipolar changeover switches.They ensure switching, transfer of sourcesor transfer of two low voltage circuits onload as well as their safety disconnection.

SIRCOVER By-Pass are manuallyoperated changeover switches.They are a combination of threeinterlocked switches enabling the use with3 + 6 pole or 4 + 8 pole.They insulate by providing simultaneoussafety isolation top and bottom and bypassing loads or low voltage circuitsmainly during maintenance operations.
