The Enerdoor FINHRM 5C series passive harmonic filter, specifically the FINHRM5C.650.B-50 model, is engineered to mitigate harmonic distortion in electrical systems. This unit operates at a nominal voltage range of 0-480 Vac and is rated for 650 Amperes.
Key technical specifications include a frequency range of 50-60 Hz and a high overload capability of 4 times the rated current for switch-on events. The filter ensures compliance with IEEE519 and EN61000-3-12 standards, reducing current THD to less than 5% with an unbalanced voltage of 2.5%. It also improves flicker and power factor.
Designed for demanding industrial applications, this filter is UL Recognized. Its climatic class is rated from -40 to +85°C, and it features a Mean Time Between Failures (MTBF) of 250,000 hours at 40°C. The IP protection rating is IP00 for currents over 210A.
Applications for this passive harmonic filter include VFDs and servo drives, processing and industrial automation, water and wastewater treatment, oil and gas operations, and HVAC systems. Its compact, open-frame or enclosed design makes it versatile for various installations.
