11RFNA910 - T/O RELAY RFNA9 6-10A

Why Choose the 11RFNA910?

The Lovato 11RFNA910 thermal overload relay provides dependable motor protection for three-phase applications. With a 6...10 A operational range, automatic resetting and a three-pole design, it mounts directly on BG06, BG09 and BG12 mini-contactors to simplify assembly. This model is non phase failure/non single-phase sensitive, delivering straightforward thermal overload protection where phase-loss detection is not required, helping safeguard motors while keeping panels compact and efficient.

Built for industrial reliability, the 11RFNA910 features IP20 frontal protection, a rated insulation voltage Ui of 690 V and an impulse withstand voltage Uimp of 8 kV. Operating between -20 and 55 °C, it conforms to IEC/EN 60947-1 and IEC/EN 60947-4-1, plus UL508 and CSA C22.2 n° 14. The compact 123 g unit is engineered for consistent performance in control panels and motor starter assemblies.
