The 110AYC10B is a 3-phase WYE RFI power line filter designed for high-noise applications requiring very high attenuation and low leakage current. It features a single-stage design with terminal block input/output connections and is rated for 110A continuous current operation. The filter operates at 50/60 Hz with a maximum phase-to-phase voltage rating of 480 VAC and phase-to-ground voltage of 277 VAC, with a maximum leakage current of 74 mA at 120 VAC 60Hz. The unit provides excellent EMI/RFI suppression across a wide frequency range, with common-mode insertion loss reaching 88 dB at 0.5 MHz and differential-mode insertion loss of 75 dB at 0.5 MHz. Its touch-safe terminals and robust construction make it ideal for EMC troubleshooting, field refurbishing, and demanding industrial power distribution applications where electromagnetic interference mitigation is critical.
