With a wide range of power contactors for switching motors, we can cover many different applications up to 250 kW. From sizes S00 to S12, in addition to 3-pole standard contactors, there are also vacuum contactors, coupling relays for optimal interfacing with the outputs of controllers, and various 4-pole power relays and miniature contactors for performance ranges up to 4 kW. The new 3RT contactors, which come in sizes S00 and S0, are particularly flexible. Apart from screw-type connections, the devices are also available throughout with spring-loaded connections. The auxiliary switches for S00, S0 and S2 can be installed for any sizes. An AC/DC version can be controlled using either AC or DC voltage and simultaneously features much lower holding power of the coils. Two auxiliary switches are already integrated in the contactors of size S0 and S2 which offer even higher contact reliability.
