The Enerdoor FINHRM.200.M is a passive harmonic filter engineered to reduce current harmonic distortion and overvoltage spikes. It operates with a nominal voltage of 400/480 Vac and a rated current of up to 200A.
Key technical specifications include an IP20 protection rating, a wide operating temperature range of -40°C to +85°C, and a high MTBF of 250,000 hours at 40°C. The filter is designed for easy connection with safety terminal blocks and improves harmonics and flicker in electrical systems.
This passive harmonic filter is suitable for applications such as variable frequency drives, woodworking machinery, packaging machinery, and printing machinery. It offers excellent attenuation of current harmonics, with THDI reduction typically below 15% and below 10% with a DC reactor.
The nominal voltage is 400/480 Vac, with 600 Vac available upon request.
The ambient temperature range is -40 to +85°C.
The packaging type is Bulk.
The rated continuous current is 200 A.
The filter supports 50 to 60 Hz.
Overload: 4x rated current on switch ON, 2x In for 10 seconds, 1.5 In for 10 minutes.
THDI is reduced to less than 15% without a DC reactor, and less than 10% with a DC reactor.
