Square D QMB-362-T Fusible Branch Switch Panelboard

Square D by Schneider Electric's QMB-362-T Fusible Twin Branch Switch Unit is a 3-pole fusible switch designed for use with QMB fusible panelboards in industrial and commercial power distribution. Rated for 60 A and up to 600 V AC, this unit provides a fuse-protected interface for feeding three-phase feeder circuits within a panel, enabling safe isolation and fault protection at the branch level. The 'T' designation identifies it as a twin unit compatible with the QMB family, and the device is UL 98 listed and CSA certified, meeting common electrical-safety requirements. The QMB fusible panelboard family supports AC and DC systems, and the QMB-362-T is positioned for use where three branch circuits require protection and switching within a 600-volt distribution network. In many commercial and light-industrial installations, it serves as a reliable branch switching solution that integrates with other QMB components to form a complete, code-compliant distribution panel. The unit’s specifications and ratings align with standards used in three-phase power delivery, providing a safe point of isolation for each branch while preserving upstream protection and coordination within the panelboard.
