The Enerdoor FINHRM 5C series passive harmonic filter, specifically the FINHRM5C.320.B-60 model, is engineered to mitigate harmonic distortion in electrical systems. This unit operates at a nominal voltage of 0-480 Vac, with an HV version available up to 690 Vac, and supports frequencies from 50 to 60 Hz. It features a rated current of 320 A and is designed to reduce current THD to less than 5%, improving power quality.
Key technical specifications include a potential test voltage of 2400 Vdc phase-to-phase and 3200 Vdc phase-to-ground. The filter offers significant overload capability, rated at 4 times the rated current for switch-on, 2 times In for 10 seconds, and 1.5 In for 10 minutes. It operates within a climatic class of -40 to +85° C, with a calculated MTBF of 250,000 hours at 40°C.
This passive harmonic filter is suitable for applications such as VFDs and servo drives, processing and industrial automation, water and wastewater treatment, oil & gas, and HVAC systems. It ensures compliance with IEEE519 and EN61000-3-12 standards, offering low power loss and operating temperature. The FINHRM5C.320.B-60 model features a busbar connection and is part of a series with rated currents from 10 to 1400 A.
