Three-phase solid state relays in the Sight-Pac series:

• For a long lifespan and large surge currents, all three-phase solid state relays use modern, highly efficient back-to-back thyristors on the output with TMS technology.
• Intended to regulate loads linked in star or delta configurations (if balanced without neutral) using three wires and three phases.
• The SSR switches two of the three phases, with the third being connected directly.
