The Enerdoor FINHRM5C.090.M-50 is a passive harmonic filter engineered to mitigate harmonic distortion in electrical systems. It operates with a nominal voltage range of 0-480 Vac and has a rated current of 90A. This filter is designed to reduce current Total Harmonic Distortion (THD) to less than 5%, improving power quality and system efficiency.
Key technical specifications include a frequency range of 50-60 Hz, a potential test voltage of 240 Vdc phase-to-phase and 320 Vdc phase-to-ground, and an IP20 protection rating. It offers overload capabilities of 4x rated current for switch-on, 2x In for 10 seconds, and 1.5 In for 10 minutes. The filter operates within a climatic class of -40 to +85°C, with a Mean Time Between Failures (MTBF) of 250,000 hours at 40°C.
This passive harmonic filter is suitable for applications involving VFDs and servo drives, processing and industrial automation, water and wastewater systems, oil & gas, and HVAC systems. Its compact, open-frame design facilitates integration into various industrial setups.
