FAQs
The QPHW1020 uses plug-on mounting with fixed terminals and is a single-pole device. To install, align the breaker with the panel bus and seating area, press firmly for a secure plug-on connection, then tighten the fixed terminals to the conductors. This design minimizes wiring errors and speeds commissioning in industrial control panels or lighting panels, while maintaining reliable connection under vibration and normal operation.
A 22 kAIC interrupt rating indicates the maximum fault current the breaker can interrupt without damage. This rating provides critical margin for industrial power systems where short-circuit currents can be high. The QPHW1020’s rating supports safer disconnection of faults on 120/240 V circuits, reducing equipment damage and enhancing overall system safety in panels and feeders.
Yes. The catalog notes specify switching duty rated for 120 V fluorescent light applications, and the HACR rating further supports safe control of lighting circuits. When selecting for lighting panels, confirm the load current (20 A) and available fault current to ensure the 22 kAIC rating provides adequate protection for your installation and maintenance plan.
The QPHW1020 is CSA Certified and UL Listed, reflecting compliance with North American safety and performance standards. Additionally, it carries HACR rating, making it suitable for air conditioning and general purpose residential or commercial electrical installations. These certifications support procurement and commissioning workflows by simplifying regulatory approvals.
Compared with other single-pole breakers, the QPHW1020 offers plug-on mounting for faster installation, fixed terminals for reliable terminations, and a robust 22 kAIC interrupt rating for higher fault protection. Its 120/240 V rating and 20 A capacity align with common control and lighting circuits, making it a cost-effective, reliable choice for retrofit projects and new panel builds in industrial settings.
