Parameters Parameter Specification Product Family Harmonic & Power Quality Solutions / De-Tuned Filters Component Type Three-Phase De-Tuned Harmonic Filter Bank Commercial Reference METSEPM3210 Primary Functions 1. Protect PFC Capacitors from harmonic resonance and overcurrent. 2. Reduce Voltage Harmonic Distortion (THDv) by providing a low-impedance path for specific harmonics. Rated Power The numeric code "3210" typically indicates the reactive power rating. This model is likely rated for 10 kvar at a standard system voltage (e.g., 400V or 480V). Always verify with official datasheet. System Voltage Typically for 400V AC (50Hz) or 480V AC (60Hz) three-phase systems. Tuning Frequency Commonly 4.2 (targeting the 5th harmonic, 250 Hz at 50 Hz base) or 6.7 (targeting the 7th harmonic, 350 Hz at 50 Hz base). Design Integrated assembly of three reactors and three capacitors (one LC pair per phase). Connection Three-phase, typically designed for delta connection of capacitors. Harmonic Mitigation Primarily effective for 5th and 7th harmonics, with some effect on higher orders. Protection Features May include internal fuses, thermal protection, and discharge resistors for capacitors. Cooling Natural convection. Enclosure Typically IP20 or IP31 for indoor cabinet mounting. Operating Temperature -5°C to +45°C (standard range for capacitor-based equipment). Standards & Certifications CE, UL, cUL, IEC 60831 (for capacitors), RoHS compliant.
