The relays are classified according to the magnitude to which they are sensitive:
  • Voltmetric relays
  • Wattmetric relays
  • Amperometric relays
  • Tachometric relays
  • Frequencymetric relays
  • Impedance relays

Through the use of transducers, these quantities may not be electrical.
A further classification is made in accordance with the principle of operation:

  • magnetic
  • thermic
  • magneto-thermic
  • induction

The static switches can be classified according to two basic types: AC switches or DC switches. The AC switches can further be divided into two categories: single-phase and three-phase.
