The MP9-21458K is a high-reliability, three-phase AC filter capacitor module designed specifically for demanding industrial drive applications. It integrates three identical 330 μF, 1000 VAC (RMS) metallized polypropylene film (EC) capacitors in a compact, mechanically robust, and thermally optimized housing. Rated for continuous operation at 1000 VAC (50/60 Hz), it meets IEC 61071 and IEC 61881 standards, with enhanced surge current capability and low ESR/ESL for effective harmonic filtering and DC-link stabilization in ABB medium-voltage and high-power converter systems (e.g., ACS800, ACS880, and HVAC drive platforms). Features include self-healing dielectric, flame-retardant UL94-V0 housing, integrated discharge resistors (≤75 V within 3 min per IEC 61881), and M12 mounting with busbar-compatible terminals. Compatible with ABB’s specified cooling requirements (forced air or liquid-cooled enclosures) and certified to RoHS/REACH.
