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



  • The insertion and disinsertion of an electrical load requires the use of a suitable switching device and protection that is safe and immune to interference.
  • Many industrial applications require the load to be activated with very short switching times in order to maintain accurate control.
  • The solution is to use solid-state relays. Gefran offers a range of solid state relay units, GTS, with current ratings between 10A and 120A and nominal voltages of 230Vac, 480Vac.
  • According to the type of load, there are Triac versions, and double SCR versions.
  • All models have been designed to guarantee continuous operation at the full current rating in an ambient temperature up to 40°C.
  • For less critical operations, it is possible to use the products at currents greater than their nominal rating (refer to the heat dissipation curves).
  • A range of accessories is available: fuses, fuse-holders, and DIN rail connections.


Zero-voltage switching. Current range: 15 A to 120A

  • Input control from logic signal
  • Switching at voltage zero crossing
  • Versions with TRIAC and with double SCR in antiparallel
  • LED power on indicator
  • MOV protections (varistor)
  • Fastening to DIN bar (standard); fastening to panel (optional)
