Mars Contactor 3P-50A-120V-BOX-LUG-A2L

Use this contactor when the equipment’s control circuit is 120V and you want the solid termination style of box lugs. In HVAC/R control panels, it enables a 120V signal from a controller to safely operate higher‑power circuits -commonly for compressors, fan motors, or staged equipment functions - without changing the original control approach. A three‑pole format allows switching multiple conductors together, which is often required in commercial equipment where coordinated switching is part of the design. Box lugs support secure, professional wiring for heavier conductors and can make field replacements cleaner and more reliable in demanding environments. The A2L designation in the item name aligns it with updated assortments where that designation influences selection. Ideal for technicians maintaining line‑voltage control strategies who want a direct, service-friendly replacement that restores proper switching and helps keep troubleshooting straightforward.
