Thermal-magnetic operation delivers fast, coordinated trips that minimize collateral outages and extend equipment life. The result is improved system reliability and reduced maintenance costs on motor loads and general distribution circuits. Application in compact panel layouts helps maximize space in crowded switchgear while maintaining easy wiring access and traceable protection for critical loads. Amperage rating of 20 A paired with a 22 kAIC interrupt capacity provides strong short-circuit protection for standard industrial feeders and motor starters, helping prevent costly damage without overtripping under normal load. This unit's two-pole, plug-on mounting and plug-on terminals simplify installation, reducing commissioning time and technician exposure during panel assembly. The 50°C calibration feature ensures protection settings remain accurate in hot environments, common in manufacturing floors and outdoor enclosures. Certifications (CSA UL) reinforce compliance, supporting audits and regulatory requirements while the 1-year warranty offers predictable after-sales support and lifecycle planning for spare parts. Non-interchangeable design minimizes cross-model confusion, ensuring consistent performance across the QPHW family and reducing stocking complexity for maintenance teams.

FAQs
QPHW2020HV is designed for plug-on mounting in two-pole industrial panelboards and distribution boards that operate at 240 V. It supports motor control centers and equipment enclosures where HACR-rated protection is required, simplifying wiring with plug-on terminals and a compact footprint. Ensure wiring polarity and terminal torque per Eaton installation guidelines to maintain protection integrity.
The device specifies a 20 A amperage rating and a 22 kAIC interrupt capacity, suitable for typical industrial branch circuits. It operates at 240 V and features a T268 trip type with 50°C calibration. These specs provide reliable short-circuit protection while accommodating standard motor and load profiles in control panels.
Yes. QPHW2020HV is HACR rated, meaning it is approved for protecting HVAC equipment and comparable loads where energy efficiency and safety are critical. This rating helps ensure selective tripping and reliable protection for HVAC accelerators, fans, and related control circuits within industrial facilities.
The breaker is CSA Certified and UL Listed, providing recognized safety compliance for North American industrial environments. These certifications support regulatory audits and help guarantee that the device meets established safety standards for electrical protection in panels, switchgear, and power distribution systems.
QPHW2020HV carries a 1-year warranty and uses a non-interchangeable design, so ensure replacement with the exact catalog number when servicing panels. Maintain proper torque on plug-on terminals, verify load ratings stay within 20 A, and confirm the circuit protection remains coordinated with upstream devices. Stocking the correct model minimizes downtime during maintenance.
