QMQB3336R - 30A, 600V, Fused Disconnect Switch

The QMQB3336R is a compact, high-performance 30A, 600V fused disconnect switch designed to deliver safe, reliable electrical isolation in demanding industrial and commercial environments. By combining switching with integrated overcurrent protection, it provides a clean, lockable disconnect point that supports essential lockout/tagout procedures and minimizes downtime during maintenance.

Designed to operate under load, this fused disconnect switch ensures dependable disconnection when you need to isolate equipment for service or repair. The fused path limits fault current, reduces arcing at switch contacts, and protects both personnel and equipment — a practical safeguard for panels, machines, and power distribution setups.

The QMQB3336R is ideal for facilities managers, electricians, and panel builders who need a reliable, easy-to-integrate isolation device. Use it on control panels for conveyors, pumps, HVAC, machine tools, or any system that requires a clear, safe disconnect with built-in protection.

What sets this model apart from generic disconnects is the built-in fusing that eliminates the need for separate fuse blocks in many layouts. The result is faster installation, fewer components, and a tidier panel that still meets safety requirements. Its robust construction is built to endure the rigors of busy industrial environments, while the compact form factor makes it a flexible choice for tight spaces.
