The Enerdoor FINHRM5C.150.M-50 is a passive harmonic filter designed to reduce harmonic distortion in electrical systems. It is rated for a nominal voltage of 0-480 Vac, with an HV version available up to 690 Vac, and operates at frequencies of 50-60 Hz. The filter has a rated current of 150A and provides significant Total Harmonic Distortion (THD) reduction to less than 5%, even with unbalanced voltage conditions.
Key technical specifications include a potential test voltage of 2400 Vdc phase-to-phase and 3200 Vdc phase-to-ground. The IP protection is rated IP20 up to 210A. Overload capability is rated at 4 times the rated current for switch-on, with specific ratings for sustained overloads. The operating temperature range is -40°C to +85°C, and it boasts a Mean Time Between Failures (MTBF) of 250,000 hours at 40°C.
This passive harmonic filter features low power loss and operating temperature. It is suitable for applications such as VFDs and servo drives, processing and industrial automation, water and wastewater systems, oil & gas, and HVAC systems. The unit is designed with an open frame for mounting and ensures compliance with IEEE519 and EN61000-3-12 standards. It also improves flicker and power factor, and is UL Recognized.
