11RFA92V3 - T/O RELAY RFA9 1.4-2.3A

Why Choose the 11RFA92V3?

The Lovato 11RFA92V3 thermal overload relay delivers dependable motor protection for three‑phase applications. This three‑pole, phase‑failure/single‑phase sensitive device features automatic resetting and an adjustable 1.4…2.3 A operational current range. Designed for fast assembly, it mounts directly on BG06, BG09 and BG12 mini‑contactors, helping you streamline panel layouts while safeguarding motors from overload and phase‑loss conditions.

Engineered for durability, it offers Ui 690 V insulation and 8 kV impulse withstand, with IP20 frontal protection and Pollution Degree 3. Rated Ith 10 A, it operates from −20 to 55 °C and up to 3000 m altitude, with storage from −55 to 70 °C. Conformity to IEC/EN 60947‑1 and 60947‑4‑1, UL508 and CSA C22.2 n° 14 underpins compliance. Approximate weight: 116 g.
