The Enerdoor FINHRM.050.M is a passive harmonic filter designed to reduce current harmonic distortion and overvoltage spikes. It operates with a nominal voltage of 400/480 Vac and has a rated current of 50A. This filter is engineered to improve harmonics, with a THDI reduction of less than 15% and less than 10% with a DC reactor.
Key features include a high attenuation indicator, safety terminal block connectors, and a climatic class of -40 to +85°C. The filter has an IP20 protection rating and a high MTBF of 250,000 hours at 40°C. It is suitable for applications such as variable frequency drives, woodworking machinery, packaging machinery, and printing machinery.
The filter utilizes terminal block connectors for safe connections. It supports solid and stranded cable sizes from 0.2 to 10 mm² with a terminal torque of 1.2 Nm and M6 terminal size. The mechanical dimension d2 is 6 mm.
