描述

818070-SF is a high-performance 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 provides space-saving installation while maintaining solid safety connector blocks for reliable electrical connections. The unit is rated for continuous operating voltages up to 3×760 VAC and supports rated currents from 10 to 230 A at 50°C, with operating frequency range from DC to 60 Hz. The filter delivers very high attenuation performance with leakage current specifications at 760 VAC/50 Hz and power loss characteristics optimized for high-efficiency applications. It is particularly suited for IT distribution networks and high-fault-current environments (100 kA SCCR per UL508), making it ideal for industrial power systems requiring robust EMC compliance and minimal ground leakage.
