Parameters Parameter Specification Product Family AccuSine / SineWave / Passive Harmonic Filters Component Type 3-Phase De-Tuned Harmonic Filter (for PFC capacitor protection) Commercial Reference METSEPM3250P Rated Reactive Power (kvar) The numeric code "3250" likely encodes the rated power. It may indicate a unit rated for 50 kvar at a standard voltage (e.g., 400V or 480V). Always verify with the official datasheet. System Voltage Typically for 400V AC (50Hz) or 480V AC (60Hz) three-phase systems. Tuning Frequency Commonly 4.2 (to mitigate the 5th harmonic) or 6.7 (to mitigate the 7th harmonic). The "P" suffix may specify this. Primary Purpose 1. Harmonic resonance protection for PFC capacitors. 2. Reduction of system voltage THD. Design Pre-assembled unit containing reactors (inductors) and capacitors per phase. Connection Three-phase, typically designed for parallel connection with the load. Protection Features May include internal fusing, thermal overload protection, and discharge resistors. Cooling Natural convection. Enclosure IP20 or IP31 cabinet for indoor installation. Operating Temperature -5°C to +45°C (typical range for capacitor-based equipment). Standards & Certifications CE, UL, cUL, IEC 60831 (Capacitors), RoHS compliant.
