• Engineered for today's most demanding commercial refrigeration and HVAC applications
• Enclosed body provides a quieter running contactor and a longer life expectancy
• Oversized 'Arch Window' to simplify wiring
• High performance copper and brass conductors maximize current carrying capability creating a cooler running contactor
• Multi-purpose Coil Terminals allow the use of QC terminals or stripped wires
• Thermoplastic housing resists dusting and contamination of the contacts to maintain maximum conductivity

Mars® 780, three pole contactors are designed for demanding applications. The enclosed body design provides quiet operation and improved durability by reducing the intrusion of dust and dirt. Side attachment rails for auxiliary switches (30 to 60 A contactors) allow attachment of Mars® 780 or furnas auxiliary switches. Silver-cadmium oxide contacts provide increased contact life when switching inductive loads.
