FAQs
The QPHW1050V uses a plug-on mounting method with plug-on terminals, simplifying installation in new panels and retrofit projects. This reduces wiring complexity, speeds up panel wiring, and minimizes terminal torque issues. For compatibility, ensure space for a single-pole device and verify panel footprint aligns with Eaton QPHW family products. Proper mounting supports stable vibration resistance in industrial environments.
A 22 kAIC interrupt rating indicates the maximum short-circuit current the breaker can interrupt without damage. This translates to higher fault energy handling, reduced arcing risk, and better protection for feeders and motors under severe fault conditions. In practice, this means greater reliability for feeders powering motors, conveyors, and other high-inrush equipment common in manufacturing facilities.
Yes. The unit is specified for 120/240 V operation and is HACR rated, making it appropriate for motor and HVAC circuits in industrial panels. The 50° C calibration helps maintain accuracy in warmer environments, and the 22 kAIC rating provides robust fault protection. For extreme environments, confirm enclosure protection and ambient conditions align with installation requirements.
This breaker is CSA Certified and UL Listed, and it carries HACR rating. These certifications simplify regulatory approvals for motor circuits and general electrical protection, facilitate code compliance, and provide traceable safety performance. For OEMs and installers, these validations reduce risk during audits and support standardized procurement across facilities.
The QPHW1050V offers predictable protection with a 50 A rating and 120/240 V operation, reducing downtime from fault events. Its plug-on design accelerates commissioning and replacements, lowering labor costs. Certifications and non-interchangeable design minimize replacement errors, protecting asset life and improving total cost of ownership in ongoing maintenance programs.
