Selecting a contactor
Select the motor rating and coil voltage separately. The coil supply must match the control circuit; it is different from the motor supply. Compare the frame size and supplied auxiliary contacts before adding the part.
Matched auxiliary blocks, suppressors and overload options are shown with the selected contactor. Swift is a Siemens Low Voltage Partner based in Heywood, Greater Manchester. Send your parts list for pricing and availability.
