Definite Purpose Contactors

Definite Purpose Contactors (DPCs) are compact, economical contactors designed for HVAC, refrigeration, and light-industrial applications. Built for high-cycle reliability, they are widely used in commercial HVAC units, heat pumps, and power circuits that require frequent switching. Kent Electrical Supply offers DP contactors from Schneider, Siemens, and Eaton with 1, 2, and 3-pole options and coil voltages from 24V to 240V.

Common Applications

  • Air conditioners and heat pumps

  • Refrigeration systems

  • Unit heaters and fan motors

  • Light industrial loads

  • Commercial HVAC controls
