Mars Contactor 3P-30A-24V-SCREW-A2L

This three‑pole contactor is a practical choice for HVAC/R equipment that uses a 24V control circuit—the most common control voltage in residential and many light commercial systems. In day‑to‑day applications, contactors are the workhorses that let a low‑voltage thermostat/controller safely command higher‑voltage loads like compressors, condenser fans, and other equipment functions. A three‑pole format can be used where you’re switching multiple power legs together or managing multi‑circuit control needs within packaged equipment. The screw terminal style supports secure field wiring during replacements and service work, especially when technicians are working with stripped conductors rather than pre‑terminated lugs. This unit is positioned as A2L‑designated in the item naming, aligning it with current product transitions where A2L considerations apply. It’s built for the practical reality of service: restore reliable switching and clean control behavior without re-engineering the control scheme.
