RU 3F15F Three-Phase AC Line Filter

Astrodyne TDI's 3F15F is a three-phase EMI line filter designed to suppress high-frequency conducted noise on 3‑phase power feeds up to 250 VAC, with a 15 A per‑phase rating. Configured for a delta three‑phase arrangement, it provides input‑side filtration for machinery such as variable-frequency drives, servo drives, and other power electronics, helping meet common EMC/EMI requirements in industrial cabinets. The model operates at 50/60 Hz and uses straightforward termination compatible with standard control‑cabinet wiring. Its compact enclosure is suitable for panel‑mount or chassis‑mount installations, enabling EMI suppression without imposing a large footprint in the electrical closet. When selecting this filter, verify that the voltage and current ratings align with your drive and supply, and consult the official datasheet to confirm mounting dimensions and terminal configurations for a proper fit in your application.
