  • High reliability and quality - Tested in excess of 1,000,000 mechanical operations
  • Rugged construction - Manufactured with heavy duty, high temperature, state-of-the-art materials
  • Compact size - Ideally suited for small space requirements in DC power equipment
  • Improved serviceability - Fewer fasteners and a more efficient design reduces time for component servicing or replacement
  • Flexible mounting and installation - The unique mounting bracket system is designed to fit many standard and custom hole patterns
  • Highly efficient magnetic circuit - Produces consistent operation in a smaller size
  • High temperature coil construction - Capable of operating at 155°C and a flame retardant rating of UL-94VO
  • Large cross section bus bars - Provides cooler operation at higher current levels
  • High temperature insulating materials - Our glass-filled thermoset materials are capable of operating in excess of 180°C
  • Silver alloy tips - New manufacturing technology produces high quality tips for extended life
  • Double break contacts - allow operating voltages of 6-72 VDC

We have a wide range of both AC and DC contactors. In our DC contactors series we have ratings from 70 to 2,000 amperes: DC 100 amp 2 pole; and in our AC series ratings from 100 to 400 amperes 3 phase.
