The 800714-SF is a three-phase EMC/RFI filter (FN 258 series) designed for three-phase inverters and power drive systems, offering industry-standard EMI attenuation based on innovative multi-stage filter topology. It features a slim space-saving book-style housing with solid safety connector blocks or optional wire output connections, and is available in multiple voltage ratings: 3x 480/277VAC for standard versions and 3x 690/400VAC for HV and HVIT versions, with rated currents ranging from 7 to 250A at 50°C. The filter operates from DC to 60Hz, provides excellent attenuation performance to ensure compliance with Class A or Class B EMC limits, and includes variants with low leakage current (P/L versions) and IT distribution network support (HVIT versions). Key technical characteristics include a maximum continuous operating voltage of 3x 480/277VAC or 3x 690/400VAC depending on variant, high potential test voltages up to 3100VDC, IP20 protection category, and an MTBF of 220,000 hours at 50°C/400V. This filter is ideal for diverse industrial applications requiring reliable EMI suppression in compact installations alongside inverters and motor drives.
