RF824200 Lovato RF82 overload relay 28-42 amp dol 18.5kw star/delta at 30kw

Why Choose the RF824200?

Lovato RF824200 is a three-pole thermal overload relay designed for reliable motor protection in three-phase installations. Phase failure/single‑phase sensitive and manually resettable, it directly mounts to BF40…BF94 contactors for compact starters. Adjustable across 28…42 A, the SKU RF824200 delivers precise overload response while safeguarding against loss of phase. An IP20 frontal rating supports dependable integration in industrial control panels.

Built to international standards, it carries IEC/EN 60947‑1 and 60947‑4‑1 conformity plus UL508 and CSA C22.2 n° 14. With Ui 690 V and 8 kV impulse withstand, the relay suits demanding panel environments. Rated Pollution Degree 3 and operable from −20 to +55 °C up to 3000 m altitude, it offers consistent performance and manual resetting for straightforward maintenance across BF-series motor starters.
