DESCRIPTION

The 800837-SF is a three-phase EMC/RFI filter designed for inverters and power drive systems, featuring a slim book-style housing that enables space-saving installation. It provides maximum continuous operating voltage of 3×520/300 VAC (standard versions) or 3×760/440 VAC (HV versions), with rated currents ranging from 7 to 250 A at 50°C and operating frequency from DC to 60 Hz. The filter delivers excellent attenuation performance through innovative multi-stage filter topology and includes solid safety connector blocks or optional wire output connections. It operates reliably across a temperature range of -25°C to +100°C, meets UL 94 V-2 flammability standards, and achieves an MTBF of 220,000 hours at 50°C/400 V. The 800837-SF is ideal for industrial applications requiring Class A or Class B EMI compliance, particularly in three-phase power distribution networks for motor drives and variable frequency drives.
