Mercury Displacement Contactors are all designed and built to meet the most exacting demands of industry.  Their service life is equal to that of the solid state contactor, even under adverse conditions of temperature, dust and moisture.   Each pole is hermetically sealed with high quality glass-to-metal seals to prevent moisture damage and voltage breakdown through the protective coating.  Mercury Contactors are available in single or multiple pole units and in several coil voltages.  Purchase the best contactors.

Advantages over mechanical contactors:

  • Superior performance and reliability for longer life and durability.
  • More compact size for easy installation.
  • Lower, predictable contact resistance.
  • Handles a variety of loads for increased design flexibility.
  • Lower coil power requirements.
  • Minimal derating due to higher ambient temperatures.
  • Quieter action.
