DESCRIPCIÓN

The 800761-SF is a three-phase book-style EMC/RFI filter designed for inverters and power drive systems, providing industry-standard EMI attenuation based on multi-stage filter topology to ensure compliance with Class A or Class B limits. It is rated for continuous operation at 3×480/277 VAC with a maximum continuous operating voltage of 480 VAC, supports rated currents from 7 to 250 A at 50 °C, and operates across a frequency range from DC to 60 Hz with an MTBF of 220,000 hours at 50 °C/400 V. The filter features a slim space-saving book-style housing with solid safety connector blocks or optional wire output connections, an IP20 protection category, and can withstand overload conditions of 4× rated current at switch-on and 1.5× rated current for 1 minute once per hour. It is designed to UL 1283, CSA 22.2 No. 8 1986, and IEC/EN 60939 standards with UL 94 V-2 or better flammability rating and high potential test voltage of 2650 VDC (P?E) for 2 seconds. Common applications include three-phase power distribution filtering for variable frequency drives, motor control systems, and industrial power electronics where EMI suppression and reliability are critical.
