Overview
The Corcom 60AYT6C F7477 is a high-performance 60A three-phase RFI/EMI filter engineered for industrial power distribution and motor control systems. Manufactured by TE Connectivity, this Corcom filter is rated for four-wire WYE (star) connection configurations and delivers reliable electromagnetic interference suppression across a broad frequency range. The unit is particularly suited to control panels, drive systems, and facility power conditioning where line noise attenuation is critical for equipment reliability.
Key Features
