Mars Contactor 3P-40A-240V-BOX-LUG-A2L

Built for systems that energize contactors with 240V control, this three‑pole, box‑lug contactor supports applications where line-voltage controls are used to command HVAC/R loads. In the field, that often means maintaining the original control philosophy of the equipment - no need to add transformers or rework control wiring - while restoring reliable switching for the main load circuit. The three‑pole format is useful for switching multiple legs together, which aligns with many packaged and commercial equipment designs. Box lugs provide a sturdy termination method for heavier conductors and are valued in service environments where secure connections and clean wire management matter. The product naming includes A2L, aligning it with updated lineups where A2L designation influences replacement choice. This is a practical replacement path when you’re matching an existing 240V coil control scheme and want a direct, service-friendly contactor with robust terminations.
