11RFNA95 - T/O RELAY RFNA9 3-5A

Why Choose the 11RFNA95?

The Lovato 11RFNA95 thermal overload relay provides reliable motor protection in three-phase applications. This non phase failure/non single-phase sensitive, three-pole device features automatic resetting and an operational current range of 3…5 A. Designed for compact assemblies, it mounts directly on BG06, BG09 and BG12 mini-contactors, streamlining installation and saving valuable panel space.

Engineered for robust performance, it offers IP20 frontal protection, rated insulation voltage Ui 690 V and impulse withstand Uimp 8 kV, with Ith 10 A. The unit operates from −20 to +55 °C up to 3000 m altitude and meets IEC/EN 60947-1, IEC/EN 60947-4-1, UL508 and CSA C22.2 n° 14, making it a dependable choice for BG-series motor starters and control panels.
