Square D QMB362T - 60A, 600V, 3-Pole, Fusible, Switch

The Square D QMB362T is a rugged 60A, 600V, 3-pole fusible switch built for demanding industrial and commercial environments. It combines dependable on/off isolation with integrated overcurrent protection, delivering a concise, maintenance-friendly solution for branch circuits and motor-related loads.

Key advantages of the QMB362T include:

• Three-pole simultaneous disconnect— safely isolate all three phases at once for straightforward maintenance and clear fault isolation.
• Fusible protection— replaceable fuses provide fast, predictable interruption during overloads or faults, safeguarding equipment and wiring downstream.
• 60A, 600V rating— designed for mid-size motor circuits and general-purpose protective switching in typical industrial power systems.
• Compact, maintainable design— streamlined fuse access and straightforward servicing reduce downtime and simplify integration into panelboards and switchgear footprints.
• Versatile integration— ideal for motor disconnects, panelboard protection, and branch-circuit protection where a compact fusible switch is required.

Ideal applications — use the QMB362T as a dedicated motor disconnect in equipment rooms, a protective stage inside control panels, or any scenario needing reliable, space-efficient fused switching on a three-phase system.

Why choose this over standalone solutions — combining isolation and overcurrent protection in a single device reduces wiring complexity, speeds maintenance, and provides coordinated protection for medium-load circuits without sacrificing performance or safety.

Practical considerations — select compatible fuse types and ratings to match motor starting and running currents, ensure proper three-phase wiring for full-phase disconnection, and plan protection coordination with upstream devices to minimize downtime during faults.
