Square D by Schneider Electric QMB-FA-3T Panelboard

Square D by Schneider Electric QMB-FA-3T Panelboard is a 100-amp, 600-volt fusible panelboard switch in the QMB family, designed for power distribution in commercial and light industrial settings. Part of Schneider Electric’s QMB fusible panelboards, it supports compact, modular interiors and is used to house fusible switches that protect feeders and branch circuits. The FA designation identifies a fusible switch assembly within a QMB panel, with interiors available for solid-neutral and bonding components to suit installation needs. The QMB line is part of Schneider Electric’s modular panelboard system, which can be configured with a mix of interior types (including QMB interiors) to tailor protection, space, and accessibility. Distributors and product catalogs commonly list the QMB-FA-3T at a 100-amp rating for 600-volt service, making it appropriate for applications where fused protection and a compact footprint are required in commercial or industrial electrical distributions.
