The description flags this as an Obs _Repl cntrl rly-contactor w/ TeSys — a replacement for an earlier control relay or contactor within the same family. If you have a legacy TeSys contactor or relay that's no longer listed, this is the drop-in intended to take its place on the DIN rail. Because it's a world service part, it's stocked for global support of installed bases. You're not chasing a discontinued orphan; this is the current-service variant meant to keep existing panels running without a redesign. The description flags it as an Obs _Repl, superseding an earlier part number. Confirm coil voltage and contact configuration match your existing wiring before installation. ## Integration Note It's sized for panel integration where space is already allocated for a contactor footprint.","metaTitle":"TeSys LX4D4SW Replacement Contactor Relay, Active","metaDescription":"Active TeSys LX4D4SW replacement control relay/contactor.
