11RFN910 - T/O RELAY RFN9 6-10A

Why Choose the 11RFN910?

Designed for dependable motor protection, the Lovato 11RFN910 thermal overload relay safeguards three-phase circuits in the 6–10 A range. This non phase failure/non single-phase sensitive, three-pole device features manual resetting and mounts directly on Lovato BG06, BG09, and BG12 mini-contactors. With robust build quality and recognised standards compliance, the 11RFN910 helps prevent overload damage while keeping installations compact and straightforward for panel builders and maintenance teams.

Rated for Ui 690 V and Uimp 8 kV, this relay offers IP20 frontal protection and Pollution Degree 3 performance. It operates reliably from −20 to +55 °C up to 3000 m altitude, with secure connections tightened to 2.3 Nm. Compliance with IEC/EN 60947-1 and 60947-4-1, plus UL508 and CSA C22.2 No. 14, supports use across global control panel standards.
