11RFA910 - T/O RELAY RFA9 6-10A

Why Choose the 11RFA910?

Designed for reliable motor protection, the Lovato 11RFA910 thermal overload relay offers phase failure/single‑phase sensitivity and automatic resetting for hassle‑free recovery. This three‑pole unit covers 6–10 A operational current and mounts directly on BG06, BG09 and BG12 mini‑contactors, streamlining panel assembly. It helps safeguard motors against overloads and phase loss, supporting dependable operation in three‑phase control applications.

Engineered for demanding environments, it features IP20 frontal protection and is rated Ui 690 V with 8 kV impulse withstand. Suitable for pollution degree 3 and operation from −20 to 55 °C, it supports installations up to 3000 m. Terminal tightening torque is 2.3 Nm. Compliance with IEC/EN 60947‑1 and 60947‑4‑1, plus UL508 and CSA C22.2 No. 14, supports assured performance.
