The Enerdoor FINHRM5C.060.M-60 is a passive harmonic filter designed to mitigate harmonic distortion in electrical systems. It operates at nominal voltages up to 480 Vac and has a rated current of 60A. This filter ensures compliance with IEEE519 and EN61000-3-12 standards by reducing current Total Harmonic Distortion (THD) to below 5%.
Key technical specifications include a potential test voltage of 2400 Vdc phase-to-phase and 3200 Vdc phase-to-ground. It offers an IP20 protection rating up to 210A and an overload capability of 4 times the rated current. 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.
Designed with an open frame, this passive harmonic filter is suitable for various industrial applications, including VFDs and servo drives, processing and industrial automation, water and wastewater treatment, oil and gas operations, and HVAC systems. Its low power loss and operating temperature contribute to efficient system performance. The filter improves flicker and power factor, making it a valuable component for power quality management.
