GS Single-phase solid state relay, up to 120A



  • Zero crossing relay with antiparallel thyristor output is the most used solid state relay in industrial applications.
  • "Zero crossing" the relay is energized when voltage meets the zero point and disenergized when current meets the zero point, depending on the signal control on the input circuit.
  • For applications with merely resistive loads, "T" version is available with TRIAC output.
  • This relay has been designed to stand for high-value transitory applications.
  • When the relay has to stand high currents for a long period, it is necessary to grant a proper dissipation and an adequate electrical connection between relay terminals and the load.
  • Varistors, fuses, thermostats and fans are available as fittings.
