Thermal-magnetic protection with a 22 kAIC interrupt rating provides fast, predictable clearing of overloads and short circuits, reducing arc flash exposure and equipment damage. This behavior translates into measurable downtime savings and safer maintenance windows in busy facilities. In practice, the QPHW2100 protects 120/240 V distribution circuits across panels, MCCs, and machine control sections, enabling OEMs to design for reliability from the start. Two-pole, plug-on mounting enables quick field installation with minimal wiring changes. The plug-on method supports clean, consistent terminations and reduces installation time by eliminating separate mounting brackets, making it ideal for panel upgrades and retrofits in existing lines. Fixed terminals provide a robust, vibration-resistant connection suitable for industrial environments. This enhances long-term stability in cabinets subject to shock or temperature cycling. The QPHW2100 fits standard enclosures while preserving labeling clarity and conductor spacing. Compliance and certifications, including UL Listed, CSA Certified, and HACR rating, help meet global codes and simplify procurement. The 1-year warranty adds lifecycle assurance as you scale protection across multiple lines. Economic and operational value comes from precise 100 A ratings and a compact footprint that supports dense panel layouts, while the non-interchangeable designation ensures you select the correct device for dedicated protection in high-availability applications.

FAQs
To install the QPHW2100, align the breaker with the panel’s bus and insert it into the slot using its plug-on mounting. Ensure the two-pole, fixed-terminal design is seated firmly, then land conductors to the fixed terminals per the panel schedule. Verify voltage rating of 120/240 V and confirm the trip setting matches the circuit amperage. Tighten terminations to the manufacturer’s torque specs and perform a functional test to confirm proper operation.
The 100 A rating indicates the continuous current the breaker is designed to carry under normal conditions. The 22 kAIC (kiloampere interrupting capacity) rating specifies the maximum short-circuit current the device can safely interrupt without damage. Together, they define the protection level for 120/240 V circuits in industrial environments, guiding proper sizing for motor loads, feeders, and protection coordination.
Yes. The HACR-rated profile makes it suitable for HVAC control circuits, while the two-pole design and 120/240 V rating accommodate many motor feeders and control panels. Its 22 kAIC interrupt capability supports short-circuit events typical in mechanical loads. Verify motor inrush, wire sizing, and coordination with downstream protective devices to ensure holistic protection.
The QPHW2100 carries UL Listed and CSA Certified marks, indicating conformance to recognized safety standards. These certifications simplify procurement for regulated environments, support compliance with electrical codes, and reassure performance guarantees for maintenance and safety programs. The HACR rating additionally aligns with energy-conscious applications, helping meet building and facility efficiency requirements.
Maintain a preventive schedule that includes periodic inspection of panel connections, verification of torque at fixed terminals, and testing of trip function during commissioning. The unit’s 1-year warranty provides initial coverage for manufacturing defects. If upgrades or relocations occur, confirm that the non-interchangeable designation remains appropriate for new configurations to preserve protection integrity.
