11RFN9075 - T/O RELAY RFN9 0.45-0.75A

Why Choose the 11RFN9075?

Designed for dependable motor protection, the Lovato 11RFN9075 thermal overload relay covers a 0.45 to 0.75 A range. This three-pole, non phase failure / non single‑phase sensitive device features manual resetting for controlled restarts. It mounts directly on BG06, BG09 and BG12 mini-contactors, simplifying compact motor starter assemblies and panel layouts while maintaining consistent performance across low-current three‑phase applications.

Engineered for harsh industrial environments, it offers Ui 690 V and Uimp 8 kV insulation strength with IP20 frontal protection. Rated Ith 10 A, Pollution Degree 3, and suitable for -20 to 55 °C operation up to 3000 m altitude, it supports reliable service in control panels. Compliance with IEC/EN 60947-1 and 60947-4-1, plus UL508 and CSA C22.2 n° 14, underpins assured quality.
