ABB 3020004R0002 Solid State Relay

ABB HDS-R2 solid-state relay, GHR 3020004R0002, is a three-phase solid-state relay from ABB’s HDS-R2 family designed to switch three‑phase AC loads from a 24 VDC control input. The 3020004R0002 designation identifies a specific 3‑pole variant within that line, intended for installation in industrial automation and control panels where solid‑state switching replaces mechanical relays. The device accepts a 24 VDC control signal, enabling direct interfacing with common PLCs and low‑voltage controllers used in manufacturing and process environments. As a three‑phase SSR, it provides electronic switching with no moving parts, offering quiet operation and reduced wear in demanding applications. This model is suited to applications requiring reliable control of three‑phase circuits while preserving a compact form factor and ABB reliability in challenging industrial settings. When selecting this part, confirm that the 3020004R0002 variant matches your system’s electrical ratings, mounting considerations, and installation requirements per ABB documentation and your project specifications to ensure proper compatibility and safe operation.
