Overview

The WEG EDP11E477GN12 is a NEMA 12 enclosed variable frequency drive (VFD) panel designed for 460VAC motor control up to 400HP. Built around the CFW11 VFD platform, this panel integrates a fused control power transformer (230/460VAC to 120VAC) and features a wall/floor-mountable enclosure with a Type 12 rating for indoor use in dusty or light washdown environments. The panel includes door-mounted operator devices: Start/Stop pushbuttons, Run and Fault pilot lights, and a VFD keypad for local control and monitoring. The main circuit breaker is equipped with a through-the-door rotary handle for safe operation without opening the enclosure. This VFD panel is optimized for flange-mounted CFW11 drives with heatsinks positioned at the rear of the enclosure for improved thermal dissipation. The EDP11 series supports both ND (normal duty) and HD (heavy duty) ratings, with the E477 model delivering 477A at 460VAC for 400HP motors. The HD/CT rating specifies 477A for 400HP operation, while the ND/VT rating allows up to 515A for 450HP applications. The panel weighs approximately 1100 lbs and is service entrance rated for NEMA 3R compliance when configured with the appropriate enclosure. Key applications include pumps, fans, compressors, and conveyors in industrial facilities where precise speed control, energy efficiency, and reduced harmonics are required. The built-in dual DC bus chokes minimize harmonic distortion, improving power quality and reducing stress on electrical infrastructure. The NEMA 12 enclosure provides protection against dust ingress and non-corrosive liquids, making it suitable for manufacturing plants, food processing, and other environments requiring IP54-level protection. The EDP11 series is part of WEG’s CFW11 drive family, which supports power ratings from 2HP to 1000HP at 460VAC, offering flexibility for a wide range of motor control applications. The panel’s standard configuration excludes a bypass contactor but includes operator devices (HOA selector switch, potentiometer, and terminal blocks) as optional add-ons. This VFD panel is ideal for retrofits or new installations where reliable, energy-efficient motor control is critical.
