It's listed under category 18401 — WORLD SERVICE PARTS — which is the manufacturer's own designation for aftermarket support spares that keep existing installations running without a full redesign. ## What the Description Means for Fit The description calls it an \"Obs _Repl cntrl rly-contactor w/ TeSys\" — shorthand for an obsolescence replacement that mates into the TeSys contactor family footprint. If you're swapping out a retired TeSys control relay or contactor, this is the drop-in intended to take its place without reworking the panel wiring or DIN-rail layout. No modification to the existing enclosure or buswork should be needed, assuming the original was a TeSys-series unit.","metaTitle":"TeSys LX4D4CW Contactor Replacement, Active Production","metaDescription":"TeSys LX4D4CW obsolescence replacement control relay/contactor.
