The MARS 61482 is a professional-grade 3-pole definite purpose contactor engineered for high-demand commercial HVACR applications. Built to handle 75 Amp inductive and 94 Amp resistive loads, this unit is a reliable solution for heavy-duty compressors, industrial motors, and large-scale heating systems. It features a 208/240V coil with Class F insulation, ensuring thermal stability during continuous operation in high-ambient environments. The MARS 61482 contactor utilizes silver cadmium oxide contacts to resist welding and minimize arcing, which is critical when switching high-current inductive loads. The enclosed body design protects internal components from dust and debris, while the large arch window box lug terminals simplify field wiring for HVAC contractors. With a compact footprint and 40 HP rating at 460/600V, this 75A DP contactor serves as a direct drop-in replacement for many OEM and aftermarket power switching components in rooftop units and chillers. Key Benefits: High Amperage Capacity: Rated for 75 FLA and 450 LRA at 240V, making it ideal for large commercial compressors. Enhanced Durability: Features silver cadmium oxide contacts for superior conductivity and extended cycle life. Installation Efficiency: Oversized box lug terminals and dual quick-connect coil terminals allow for fast, secure terminations. Quiet Operation: The fully enclosed housing reduces contactor "chatter" and prevents the intrusion of environmental contaminants. Broad Compatibility: Standard mounting footprint allows for easy replacement of Furnas, Square D, and other major brands. Common Questions: What is the maximum horsepower rating for this contactor? The MARS 61482 is rated for 25 HP at 230V, 40 HP at 460V, and 40 HP at 600V in three-phase applications. Does this unit include a manual push-to-test button? No, typical of 75A and 90A high-amperage models, the 75-amp frame does not include the recessed push-to-test feature found on smaller 30-60 amp contactors. Can I use this for a 208V control circuit? Yes, the coil is rated for a 208/240V range, making it compatible with standard commercial control voltages.
