描述

The 820858-SF is a high-voltage three-phase EMC/RFI filter designed for inverter and power drive systems operating at 690 VAC. This filter features a compact book-style housing that minimizes footprint space while providing high attenuation performance for electromagnetic interference suppression. It is rated for continuous operation at 760 VAC (3-phase) with a maximum continuous operating voltage of 3×760/440 VAC, and operates across DC to 60 Hz frequency range. The filter incorporates solid safety connector blocks and is available in standard and high-performance configurations to meet various EMC requirements. With an MTBF exceeding 200,000 hours and a short-circuit current rating (SCCR) of 100 kA per UL508, this filter is suitable for demanding industrial applications including variable frequency drives, motor control systems, and power distribution networks requiring reliable RFI suppression.
