DESCRIPTION

The 800824-SF is a three-phase EMC/RFI filter from the FN 258 series designed for inverters and power drive systems, featuring a slim space-saving book-style housing that enables convenient installation next to motor drives. It provides state-of-the-art EMI attenuation based on multi-stage filter topology to ensure compliance with Class A or Class B EMC limits, with rated currents ranging from 7 to 250 A at 50°C and maximum continuous operating voltage of 480 VAC (3x 480/277 VAC). The filter incorporates solid safety connector blocks or optional wire output connections, excellent attenuation performance, and is available in standard (FN 258), high-voltage (FN 258HV up to 690 VAC), and low-leakage variants (FN 258L and FN 258P). It is designed for three-phase variable speed drives, power distribution networks, and energy conversion applications where reliable EMI filtering and compliance with international standards (UL 1283, IEC/EN 60939) are essential.
