Information About GP8-2774ML-20
The GP8-2774ML-20 is a Grafik Eye GP Series dimming panel manufactured by Lutron for commercial lighting control systems. It features eight load circuits with 20 A branch circuit breakers and is designed for 277/480 V, 50/60 Hz, 3-phase, 4-wire electrical distribution. The unit utilizes a main lugs only (MLO/ML) feed configuration and is enclosed in a NEMA Type 1 housing for indoor installation. A patented ribbed aluminum heat sink enables convection cooling without fans, and the integrated 10-year power failure memory restores the last selected lighting scene after power interruptions.
