Why Choose the RFE450200?
Designed for precise motor protection, the Lovato RFE450200 electronic thermal overload relay safeguards three‑phase circuits from overloads and phase loss. This three‑pole unit covers 0.4...2 A and offers manual or automatic resetting. Phase failure/single‑phase sensitivity enhances reliability, while direct mounting on BF09… BF38… contactors streamlines assembly and reduces panel space.
Built to international standards, it features Ui 1000 V and Uimp 6 kV, with IP20 frontal protection and Pollution Degree 3. Rated Ith 10 A, it operates from −25 to 70 °C up to 3000 m altitude. Conforms to IEC/EN 60947‑1 and 60947‑4‑1, with UL and CSA counterparts, ensuring dependable performance across compliant control panels.
