GE Spectra Series MLO Panelboard is a main-lug distribution panelboard rated for 480Y/277V and up to 1600A in a 3‑phase, 4‑wire configuration. As a Main Lug Only (MLO) design, it does not include a built-in main breaker and is fed by upstream overcurrent protection. This GE panelboard provides a distribution point for branch circuits in 480V three‑phase systems and is part of the Spectra Series family for industrial and commercial power distribution. Use this panelboard where a main-lug arrangement is required to accommodate large-load feeders.
