The Enerdoor FINHRM5C.470.B-60 is a passive harmonic filter designed to reduce harmonic distortion in electrical systems. It operates at a nominal voltage of 480 Vac and has a rated current of 470 A.
This filter ensures compliance with IEEE519 and EN61000-3-12 standards, significantly reducing current THD to less than 5%. It also improves flicker and power factor, contributing to overall power quality. The filter features low power loss and a compact, open-frame design.
Key specifications include a potential test voltage of 240 Vdc phase-to-phase and 320 Vdc phase-to-ground. It operates within a climatic class of -40 to +85° C and has an IP00 protection rating for currents over 210 A. The MTBF at 40°C is rated at 250,000 hours.
Applications for this passive harmonic filter include VFDs and servo drives, processing and industrial automation, water and wastewater systems, oil & gas, and HVAC systems.
