11RFA915 - T/O RELAY RFA9 9-15A

Why Choose the 11RFA915?

Lovato’s 11RFA915 thermal overload relay delivers dependable motor protection with phase failure/single‑phase sensitivity in a compact, three‑pole design. Factory set for automatic resetting, it covers an adjustable 9…15 A range to suit common three‑phase loads. Designed for direct mounting on BG06, BG09 and BG12 mini‑contactors, it streamlines panel assembly while maintaining IP20 frontal protection and robust dielectric performance.

Rated Ui 690 V with 8 kV impulse withstand, the 11RFA915 is engineered for industrial reliability and compliance with IEC/EN 60947-1, IEC/EN 60947-4-1, UL508 and CSA C22.2 n° 14. It operates from −20 to 55 °C up to 3000 m altitude, with Pollution Degree 3 and IP20 front, offering a balanced mix of safety, performance and straightforward installation.
