Why the QOH2100 stands out in industrial protection

In industrial settings, consistent protection is non-negotiable. The QOH2100 delivers precise, predictable tripping behavior at 100 A, helping to shield wiring and equipment from overcurrent events. Its 2-pole design ensures both live conductors disconnect together, reducing shock risk and simplifying safe shutdown during faults or maintenance.

Practical use cases

• Guarding 240V feeders that power conveyors, presses, and other heavy-duty machinery on manufacturing floors.
• Replacement or upgrade in existing Square D panels where a 100 A, 2-pole, 240V breaker is required.
• Maintenance projects that demand reliable, readily sourced perimeter protection for critical loads.

Tips for installation and selection

Always verify fit by part number and the specific application requirements of your panel. If you’re unsure about compatibility, reach out with your setup details and we’ll help confirm whether the QOH2100 is the right match for your distribution panel and circuit credentials.
