RS PRO Solid State Relay, 50 A Load, Surface Mount, 600 Vrms Load, 32V Control

RS PRO Three-Phase Solid-State Relay

Use these three-phase solid state relay devices from RS PRO to control three-phase electrical power systems. A three-phase SSR consists of multiple solid-state switching elements arranged in a configuration that can handle three-phase AC power. During applications, when the control circuit receives the appropriate control signals, it triggers the corresponding switching elements in each phase. This allows the three-phase power to flow through or be interrupted based on the control input.

Why Would You Choose These Solid-State Relays?

RS PRO SSR relays are widely used in industrial switching applications such as control of heaters, motors, solenoids, lighting, and microcontroller-based systems. SSR switching is preferred due to its high reliability and long life in an electrically harsh environment. Ratings are offered starting from 10 A, 25 A, 40 A, and 50 A for 480 V and 600 V applications.
