RF975 Lovato RF9 overload relay BG mini contactors 4.5-7.5 amp 2.2 kw

Why Choose the 11RF975?

Lovato 11RF975 is a thermal overload relay for reliable motor protection, phase failure/single‑phase sensitive. This three‑pole, three‑phase device features manual resetting and an adjustable 4.5…7.5 A setting range. It mounts directly on Lovato BG mini‑contactors (BG06, BG09, BG12), streamlining panel assembly and supporting coordinated performance with the BG series.

Designed for dependable service, the relay offers IP20 frontal protection, Ui 690 V and Uimp 8 kV, with Ith 10 A. It operates from -20 to 55 °C, up to 3000 m altitude, Pollution Degree 3. Built to IEC/EN 60947-1 and 60947-4-1, and recognised to UL508 and CSA C22.2 n° 14.
