11RFA95 - T/O RELAY RFA9 3-5A

Why Choose the 11RFA95?

Lovato 11RFA95 is a thermal overload relay designed for reliable motor protection in three‑phase systems. Phase failure/single‑phase sensitive and three‑pole, it provides 3…5 A protection with automatic resetting. The unit mounts directly on BG06, BG09 and BG12 mini‑contactors, simplifying panel layouts and wiring. With an IP20 frontal rating and Ui 690 V, Uimp 8 kV, it supports robust industrial control applications.

Built for demanding environments, the relay carries Pollution degree 3 and a thermal current Ith of 10 A. Operating temperatures span -20 to 55 °C, with storage from -55 to 70 °C, and installation up to 3000 m altitude. Terminal tightening torque is 2.3 Nm. Conforms to IEC/EN 60947-1, IEC/EN 60947-4-1, UL508 and CSA C22.2 n° 14, with a compact 116 g form.
