The Enerdoor FINHRM5C.750.B-50 is a passive harmonic filter engineered to mitigate harmonic distortion in electrical systems. It operates within a nominal voltage range of 0-480 Vac and supports a frequency of 50-60 Hz, with a rated current capacity of 750A.
This filter is designed to reduce current total harmonic distortion (THD) to less than 5%, even with unbalanced voltages up to 2.5%. It improves flicker and power factor, contributing to overall power quality. The filter features an IP00 protection rating for currents over 210A and an operating temperature range of -40 to +85°C.
Key technical specifications include a potential test voltage of 240 Vdc phase-to-phase and 320 Vdc phase-to-ground. It offers overload capability of 2 times the rated current for 10 seconds and 1.5 times for 10 minutes. The filter has a low power loss of 437W at 480 Vac and 400 Vac.
Applications for this passive harmonic filter include VFDs and servo drives, processing and industrial automation, water and wastewater systems, oil & gas, and HVAC systems. It is suitable for end-user facilities requiring improved power quality.
