Schneider Electric QMB-306-T Fusible Disconnect Switch

Schneider Electric’s QMB306-T is a three‑phase, fusible panelboard switch rated for 60 A at 240 V, designed to provide a reliable disconnect with integrated fuse protection for Square D QMB panelboards. This 3‑pole unit serves as both the disconnect and fuse carrier in a compact package suitable for commercial and light industrial panelboard applications, and it accepts QMB-series fuses with the appropriate fuse kits. It can be configured for Class R fuses (with the proper kit) and is compatible with Class J, L, or T fuses when the corresponding fuse kit is installed. The QMB306-T delivers substantial fault-current protection, with an interrupt rating up to 200 kA at 240 V, helping to limit short‑circuit energy in typical 3‑phase installations. Common uses include feeding and isolating small motors, HVAC equipment, or feeder circuits within panelboard enclosures, providing a code‑compliant, hands‑on disconnect for servicing and safety within Schneider Electric’s QMB family."
