The Enerdoor FINHRM5C.320.B-50 is a passive harmonic filter engineered to mitigate harmonic distortion in electrical systems. It operates at a nominal voltage of 0-480 Vac and has a rated current of 320A. This filter is designed to reduce current Total Harmonic Distortion (THD) to less than 5%, ensuring compliance with standards like IEEE519 and EN61000-3-12.
Key features include a UL Recognized component status, an IP20 protection rating up to 210A, and an IP00 rating for currents over 210A. The filter operates within a climatic class of -40 to +85°C and boasts a Mean Time Between Failures (MTBF) of 250,000 hours at 40°C. Its overload capability is rated at 4 times the rated current for switch-on, 2 times In for 10 seconds, and 1.5 In for 10 minutes.
This passive harmonic filter is suitable for applications such as VFDs and servo drives, processing and industrial automation, water and wastewater systems, oil & gas, and HVAC systems. It is available in a compact, open-frame case.
The FINHRM 5C series offers excellent THD reduction, improving flicker and power factor. Typical measurements show a significant reduction in THD current distortion when the filter is in use, compared to systems without filtering.
