QMQB1136R is a robust 3-pole fusible switch engineered for reliable isolation and overcurrent protection in tough industrial settings. With a 100A rating and 600V capability, it handles demanding three-phase power safely and efficiently.

Key specifications

• Model: QMQB1136R
• Amperage: 100A
• Voltage: 600V
• Poles: 3-Pole
• Fusible: Yes (fusible switching element)

Designed for practical, on-the-spot isolation and protection, this switch is ideal wherever you need a compact, maintainable solution that combines a disconnect with current-limiting fuse protection.

What this means in real-world use

• Motor disconnects: Quickly isolate three-phase motors for maintenance while ensuring a safe, controlled shutdown of all conductors.
• Panelboards and control panels: Integrate inline protection without adding separate fusing blocks, reducing panel complexity and potential fault points.
• Branch circuit protection: Protect feeders and downstream equipment from overcurrent while providing a clear shutoff point.

Why it stands out

• Integrated fusible protection: The fusible element provides inherent overcurrent protection aligned with the disconnect function, simplifying panel layout and maintenance schedules.
• Rugged, industrial-ready design: Built for steady operation in demanding environments where reliability matters most.
• Compact and maintainable: A space-efficient solution that’s straightforward to inspect, service, and replace when needed.

Ideal for

• Facilities with three-phase motors, conveyors, pumps, fans, HVAC equipment, and other heavy loads.
• Electrical rooms and control panels requiring a dependable, easy-to-service protective switch.

Tips for optimal performance

• Match the fuse element to your motor’s starting current and inverter compatibility; consult your motor datasheet to select appropriate protection without nuisance trips.
• Wiring should meet your system’s ampacity and conductor sizing, ensuring secure terminal connections and compliance with your installation standards.
• Implement safe maintenance practices: always de-energize and lockout/tagout before inspecting or replacing the fuse assembly.

Upgrade your electrical protection with QMQB1136R for a streamlined, reliable, and maintainable solution that keeps your three-phase equipment safe, accessible, and ready for operation.
