Information About QMB367MW
The QMB367MW is a fuse-switch disconnector from the Square D QMB Series E1–E2 product family. It is constructed for panel-mounted installation and serves as a main or feeder disconnect within panelboards and distribution equipment. The switch is designed to operate with Class R fuses, providing controlled isolation and overcurrent protection. It is typically installed in indoor electrical distribution systems where high interrupt capacity and reliable manual disconnect functionality are required.
Key Features:
- Fusible disconnect design: Combines switching and fuse-based overcurrent protection.
- High current capacity: Rated for 800 A continuous operation.
- Three-pole configuration: Supports three-phase electrical systems.
- Class R fuse compatibility: Allows use of high-performance current-limiting fuses.
- Panel-mounted construction: Designed for integration into QMB panelboards.
- High interrupt capability: Supports high fault current environments.
The QMB367MW delivers the reliability and precision required for high-capacity power distribution and safe circuit isolation in commercial and industrial electrical systems.
