Sylvania QMBFP3036 – 100A/100A, 600V, 3-Pole Twin Fusible Switch – QMBF Series

Engineered for demanding electrical environments, the Sylvania QMBFP3036 delivers dual-circuit protection with a compact footprint. This 3-pole twin fusible switch guards two independent 100A circuits at up to 600V AC, all inside a single rugged enclosure. If you’re configuring panelboards or upgrading switchgear, this unit provides reliable dual disconnect capability and streamlined installation in one integrated package.

Exceptional dual-circuit protection in one compact enclosure

• Twin 100A/100A rating—protect two circuits without sacrificing space or wiring complexity.
• 600V, 3-pole fusible design—ensures safe switching, reliable overload protection, and dependable short-circuit response.
• Space-saving twin configuration—reduces enclosure footprint and simplifies wiring runs in crowded electrical rooms.
• Industrial-grade construction—built to withstand the rigors of commercial, industrial, and utility environments for long service life.
• Direct compatibility with QMBF series panelboard and switchgear assemblies—seamless integration without custom mounting or adapters.

Applications and use cases

The QMBFP3036 is ideal for dual-circuit distribution needs where space and reliability matter. Use it in panelboards and switchgear assemblies that require separate protection for two feeders or circuits, such as mezzanine distribution runs, submetering feeders, or critical loads that benefit from a fast, reliable disconnect. Its robust construction makes it well-suited for environments that demand consistent performance, from commercial facilities to industrial plants and utility-grade applications.
