Parameter Specification Product Family Harmonic & Power Quality Solutions / AC Line Reactors Component Type 3-Phase AC Line Reactor (Input Choke) Commercial Reference METSEPM5320 Compatible Load Current 20 A (RMS, at specified voltage and frequency) Design Voltage Typically for 400/480V AC, 50/60 Hz systems (confirm exact voltage rating from official datasheet). Frequency 50/60 Hz Inductance Specific value depends on the impedance percentage. For a common 3% impedance reactor at 480V, the inductance per phase is approximately 0.22 mH (Calculated: L = (Z% * V_LL) / (100% * √3 * 2π * f * I)). Always verify with official data. Impedance Commonly available in standard percentages such as 3% or 5% at rated current and voltage. Current Rating Continuous: 20 A RMS Overload Capacity: Typically 150% for 1 minute. Insulation Class Class F (155°C) or higher. Temperature Rise Typically ≤ 80°C at rated current. Cooling Natural convection (air-cooled). Connection Screw terminals suitable for copper conductors. Mounting Chassis or DIN-rail mountable (depends on specific model/enclosure variant). Enclosure Protection Typically open style (IP00) for cabinet mounting. Operating Temperature -25°C to +55°C (ambient, with derating above 40°C). Storage Temperature -40°C to +85°C. Standards & Certifications CE, UL, cUL, RoHS compliant. Designed in accordance with IEC 60076-6, EN 61558.
