Load Centers & Panelboards

Load Centers & Panelboards — New & Used

Load centers and panelboards distribute power and provide branch-circuit protection across facilities and equipment. Available as main-breaker or main-lug configurations with copper or aluminum bus, they support single-phase (120/240 V) and three-phase (208Y/120, 480Y/277 V) systems with common amp ratings from 100–600 A. Indoor NEMA 1 and outdoor NEMA 3R enclosures, field-installable kits, and breaker options make these panels flexible for OEM builds, expansions, and MRO.

At Surplus Select, we stock a rotating mix of new and used OEM load centers and panelboards from brands like Square D/Schneider, Siemens, Eaton/Cutler-Hammer, GE, and ABB. Listings reflect live inventory with surplus pricing on cabinets, interiors, trim, and compatible breakers.
