  • Product Description:

    The SGT8658502 three-phase solid-state relay has 3x 24 amp / 24-520Vac solid-state outputs controlled by a single 24-255Vac/dc input. Designed for endurance and reliability in harsh industrial applications, the SGT8658502 utilizes rugged back-to-back (inverse parallel) SCRs to switch power to AC loads, enhancing the relay’s ability to withstand heavy surge currents and ensuring overall reliability. 


    The SGT8650810 is pre-assembled onto a thermally efficient, DIN mount heat sink and ready for installation. The assembly is fully derated to 24 amps per-phase in a 40°C ambient temperature with proper ventilation.  


    Input and output over voltage protection are standard on the SGT8658502. A green LED provides visual indication that the input/control signal is applied to the solid-state relay. 


    The SGT8658502 solid state relay is an ideal solution for switching  three-phase resistive loads and motor loads (12A per-phase AC-53 rating). 


    A heat sink and thermal compound are normally required to prevent a solid state relay from overheating during normal operation. HBControls offers a wide range of thermally efficient, DIN and panel mount heat sinks suitable for use with Celduc solid-state relays.
