QMQB3332R - 30A, 240V, 3-Phase, Fusible, Switch

The QMQB3332R is a robust 30A, 240V, 3-Phase Fusible Switch designed to deliver reliable on/off isolation with built-in overcurrent protection in tough industrial and commercial environments.

Rather than a plain disconnect, this unit combines safe switching with dependable fuse protection, guarding motors, drives, and downstream equipment from overloads and short circuits while simplifying maintenance and compliance requirements.

Key advantages

• Compact, maintainable fusible switch: streamlined design that fits into tight panel spaces and allows quick fuse changes without sacrificing protection.
• Three-phase, 240V operation: ideal for motor control, conveyors, pumps, and HVAC equipment that rely on balanced three-phase power.
• 30A current rating with fusible protection: provides reliable disconnect and overload protection at a single, accessible point in the circuit.
• Motor disconnect and panelboard protection: serves as a dedicated fused disconnect for critical equipment and for protecting branch circuits.

Where it shines

Ideal for factory automation lines, machine control panels, and commercial equipment rooms where a compact, maintainable switch is needed—combined with fuse-based protection. Perfect for:

• Motor disconnects on fans, pumps, compressors, and small drives
• Panelboard sections requiring a dedicated fused disconnect
• Branch circuit protection in machines and process equipment

How it works and practical benefits

With a clear on/off mechanism and a fused path, the QMQB3332R lets you safely de-energize a circuit for service while providing immediate protection against overloads. The fuse design supports straightforward replacement, reducing maintenance downtime and helping you implement safe, compliant lockout/tagout practices during servicing.
