Mercury Displacement Relays are used in industry where rapid on off switching of loads is essential to control a process. Applications include Heating elements, Motor loads, 'Tungsten lamps, or other inductive or resistive loads. Mercury Displacement Relays can have typical operate times of 50 milliseconds and release times of 80 milliseconds.

These Mercury Displacement Relays are capable of millions of cycles and can be used in operating temperatures from -35ºC to +85ºC. Mercury Displacement Relays are available in 1, 2, 3, and 4, poles and in a current handling capacities of 20, 35, 60, and 100, amps. Various coil voltages both AC or DC are available with operating voltages up to 600 volts. Most sizes in Stock.

Mercury Displacement Relays Features:

  • Longer life and high reliability with low contact resistance

  • Compact size for large current loads

  • Rapid On Off cycling possible

  • High voltages up to 600 VAC available

  • Quite action low noise levels

  • No external arcing as contacts are hermetically sealed

  • Minimum moving parts and low coil power requirements
