The solid‑state overload relays RWB are suitable to protect motors in a wide range of industrial applications including those where long starting time is required. This way, motors on low, medium or heavy‑duty applications can be properly protected just by selecting the proper trip class (10, 20 or 30 according to IEC 60947‑4‑1) in the DIP‑switches. The solid‑state overload relay can be directly mounted on WEG Contactors (CWB lines).
