Mars Definite Purpose Contactor Coil Contactors

Mars definite purpose contactors are electromechanical switches for HVAC and refrigeration control circuits. A low-voltage control signal switches high-current loads such as compressors, condenser fans and other motors. They suit residential and commercial air conditioning, heat pump, refrigeration and electric heating systems, and they work as replacement contactors.

Key Features:

• Designed for refrigeration, air conditioning and electric heating systems
• Enclosed body design for quieter operation and longer service life
• Oversized arch window and box lug terminals make wiring easier
• Copper and brass conductors maximize current-carrying capability and help the contactor run cooler
• Multi-purpose coil terminals accept quick-connect terminals or stripped wires
• Removable coils allow field replacement of a damaged coil
• Removable cover gives full access to the contacts
• Thermoplastic housing resists dust and contamination of the contacts to maintain conductivity

Pole count, amperage rating and coil voltage vary by model. Select the variant that matches your system's load and control voltage requirements.
