Feature → Business Impact → Application: Thermal-magnetic protection provides prompt interruption during overloads and short circuits, reducing equipment wear and unplanned downtime in heavy-use panels. This translates to improved reliability for manufacturing lines and critical process controls, enabling safer startups and predictable maintenance windows. Application: industrial panelboards, MCCs, and distribution feeders requiring dependable, code-compliant protection. Feature → Business Impact → Application: A 42 kAIC interrupt rating supports high fault current environments, minimizing arc flash risk and catastrophic failures. This improves safety metrics in plants with large motors or high-energy feeders and reduces insurance exposure. Application: large facilities with powerful feeders and critical line-side protection needs. Feature → Business Impact → Application: 100 A current rating paired with fixed terminals and plug-on mounting streamlines installation and future maintenance. The result is faster commissioning, easier retrofits, and lower labor costs during panel upgrades. Application: new builds and retrofits in commercial and light-industrial settings. Feature → Business Impact → Application: HACR-rated performance covers HVAC and related equipment, ensuring compliant protection for a broad range of loads. This supports standardization across facilities and minimizes mis-selection risk. Application: OEM controls, HVAC distribution panels, and commercial building systems. Feature → Business Impact → Application: UL Listed and CSA Certified with a 1-year warranty provides procurement confidence, traceability, and predictable support. This reduces supplier risk and helps meet regulatory procurement requirements. Application: end-user facilities, contractors, and spec-driven projects.

FAQs
The QHPX2100 is designed for industrial panelboards, motor control centers, and distribution feeders requiring robust two-pole 120/240 V protection. With plug-on mounting and fixed terminals, it simplifies field retrofit and new installations, delivering reliable circuit protection while reducing wiring time and potential connection issues.
A 42 kAIC interrupt rating means the breaker can interrupt high-energy fault currents without tripping the upstream protection or sustaining damage. This reduces the risk of arc flash events, minimizes equipment damage, and enhances overall system reliability in facilities with large motors and high fault levels.
The QHPX2100 is the QHPX type circuit breaker with two-pole, plug-on mounting. It is designed for compatibility within the QHPX family and features fixed terminals for secure connections. It is not a direct interchange for non-QHPX models, so verify the panelboard compatibility before replacement.
This model is UL Listed and CSA Certified, and HACR rated, ensuring compliance with major North American electrical codes. These certifications provide procurement confidence, risk mitigation for audits, and assurance that the device suits HVAC and general commercial/industrial loads.
The QHPX2100 carries a 1-year warranty from date of purchase. Routine maintenance is minimal beyond periodic visual inspections and torque checks on fixed terminals. For critical installations, maintain spare units and verify compatibility during panel upgrades to minimize downtime.
