MP9-21499K Rev.B EC Capacitor — 3×365 µF, 1000 VAC / 1400 VDC for ABB Converters

The MP9-21499K Rev.B is a high-reliability, three-phase, stacked-film (EC) capacitor module designed specifically for demanding industrial drive applications. It comprises three identical 365 µF capacitor units housed in a single compact, mechanically robust enclosure — totaling an effective 3×365 µF configuration. Rated for continuous operation at 1000 VAC (50/60 Hz) and peak DC voltage up to 1400 VDC, it meets stringent requirements for ABB medium-voltage and high-power converter systems (e.g., ACS800/ACS880 series, MV drives, and regenerative front-end rectifiers). Features include self-healing metallized polypropylene (PP) film dielectric, integrated discharge resistors (typically ≤1 kΩ per phase, <60 s to <50 V), low ESR/ESL, high ripple current capability (≥12 Arms per phase @ 10 kHz), and UL/IEC 61071 & IEC 61881-1 compliance. Mounting is optimized for forced-air or liquid-cooled cabinets with M8 terminals and vibration-damped baseplate.
