The Enerdoor FINHRM5C.260.B-60 is a passive harmonic filter with a rated current of 260A and a nominal voltage of 480V. This filter is engineered to reduce total harmonic distortion (THD) to less than 5%, ensuring cleaner power in industrial applications.
Key electrical specifications include a phase-to-phase test voltage of 2400Vdc and phase-to-ground of 3200Vdc, both for 2 seconds. It boasts an overload capability of 4 times the rated current for switch-on, 2 times the rated current for 10 seconds, and 1.5 times the rated current for 10 minutes. The filter operates within a climatic class of -40 to +85°C and has a calculated MTBF of 250,000 hours at 40°C.
Designed for open frame mounting, this passive harmonic filter is suitable for various applications including VFDs and servo drives, processing and industrial automation, water and wastewater systems, oil & gas, and HVAC systems. It ensures compliance with IEEE519 and EN61000-3-12 standards, offering low power loss and operating temperature.
IP protection is rated at IP20 up to 210A and IP00 for currents over 210A. The filter improves flicker and power factor, making it a robust solution for power quality management.
The nominal voltage rating is 480V, with an HV version available for 690V.
The rated current is 260A.
It reduces current THD to less than 5%.
The operating temperature range is -40 to +85°C.
The IP protection rating is IP20 up to 210A and IP00 over 210A.
Typical power loss is 710W at 400V and 852W at 480V.
