FAQs
QHPX3100H uses a plug-on mounting method with fixed terminals and a three-pole configuration, designed for Eaton QHPX-compatible panelboards. Ensure the panel has adequate space and bus bar alignment, and replace only with the same catalog series to preserve coordination and interrupt ratings. Confirm 240 V system compatibility and consider adjacent circuit protection to maintain overall panel protection strategy.
Key specs include a 100 A amperage rating, 42 kAIC interrupt rating, voltage rating of 240 V, and a three-pole configuration with fixed terminals. The device supports plug-on mounting and is HACR rated, with CSA Certified and UL Listed safety certifications. These parameters guide proper protection sizing, coordination, and compliance in industrial panels.
Yes. The QHPX3100H is HACR Rated, a designation for breakers used with HVAC equipment and motor-control circuits. This ensures safe, code-compliant operation in temperature-controlled environments and helps simplify electrical design by aligning protective devices with HVAC and motor loads.
The QHPX3100H is specified as Non-Interchangeable within its options, so compatibility should be verified against the exact catalog number. When upgrading or replacing, match the catalog number, pole configuration, mounting method, and voltage/amperage requirements to ensure protective coordination and UL/CSA compliance.
The unit carries a 1-year warranty from installation or shipment, with typical maintenance focused on routine panel inspection, torque checks on terminals, and confirming trip history aligns with load changes. Regular maintenance helps sustain protection performance, prolong equipment life, and minimize unexpected downtime.
