11RFNA915 - T/O RELAY RFNA9 9-15A

Why Choose the 11RFNA915?

The Lovato 11RFNA915 thermal overload relay delivers dependable three‑phase motor protection in the 9…15 A range. This three‑pole, non phase failure / non single‑phase sensitive unit features automatic resetting to minimise downtime. Designed for direct mounting on Lovato BG06, BG09 and BG12 mini‑contactors, it streamlines panel assembly and saves space. With IP20 frontal protection, it’s an efficient choice for compact control panels and OEM builds.

Engineered to international standards, including IEC/EN 60947‑1 and 60947‑4‑1, UL508 and CSA C22.2 n° 14, it offers robust electrical performance. Rated Ui 690 V and Uimp 8 kV, with IP20 frontal protection, it performs reliably from -20 to 55 °C. Ideal for safeguarding motors within the specified operational current, while integrating seamlessly with the Lovato BG contactor platform.
