RF380160 Lovato RF38 overload relay 1-1.6 amp 0.55 kw

Why Choose the RF380160?

Designed for dependable motor protection, the Lovato RF380160 thermal overload relay safeguards three-phase applications with phase failure/single‑phase sensitivity. The three‑pole unit covers a 1.0…1.6 A setting range and offers manual or automatic resetting. Optimised for straightforward installation, RF380160 mounts directly on BF09–BF38 contactors, helping reduce panel space and wiring while delivering fast response to overload conditions.

Engineered to IEC/EN 60947-1 and 60947-4-1, with UL508 and CSA approvals, this relay provides robust insulation at Ui 690 V and Uimp 6 kV. A frontal IP20 degree and -25 to 60 °C operating range support reliable service up to 3000 m altitude. Clear terminals with 2 to 2.5 Nm tightening torque aid secure wiring, while the compact 160 g body suits modern control panels.
