GQ Single-phase solid state relay, up to 90A



  • Zero crossing relay with antiparallel double SCR output is the most used solid state relay in industrial applications.
  • In fact, it can be used for resistive, inductive, and capacity loads.
  • "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.
  • 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.
  • Heatsinks, plug-in connectors, varistors, fuses, thermostats and fans, and adhesive dissipating strips, are available as fittings.
