The Enerdoor FINHRM.100.M is a passive harmonic filter engineered to mitigate current harmonic distortion and overvoltage spikes in electrical systems. It is designed for nominal operation at 400/480 Vac and can handle up to 600 Vac upon request. With a rated current of 100A, this filter offers significant THDI reduction, achieving less than 15% and even below 10% when used with a DC reactor.
Key electrical specifications include a dielectric strength of 2400 Vdc phase-to-phase and 3200 Vdc phase-to-ground. The filter is built to withstand overload conditions, capable of handling 4 times the rated current upon switch-on and 2 times the rated current for 10 seconds. It operates within a wide climatic class range of -40°C to +85°C, ensuring reliability in various environmental conditions. The MTBF is rated at 250,000 hours at 40°C.
Mechanical and electrical connections are facilitated by safety terminal block connectors. The filter supports solid and stranded cable sizes from 10 to 50 mm², with a terminal torque specification of 4 Nm for M6 terminals. Its IP20 protection rating indicates suitability for environments where protection against solid objects greater than 12.5mm is needed.
This passive harmonic filter is suitable for applications such as variable frequency drives, woodworking machinery, packaging machinery, and printing machinery, where harmonic mitigation is crucial for system performance and longevity.
The nominal operating voltage is 400/480 Vac, with 600 Vac available upon request.
The operating temperature range is -40°C to +85°C.
The filter is supplied in bulk packaging.
The rated current is 100A (the datasheet specifies a range of 16 to 200A for the series).
THDI is reduced below 15% without a DC reactor, and below 10% with a DC reactor.
The mean time between failures (MTBF) is 250,000 hours at 40°C.
The enclosure is rated IP20.
