Thermal-magnetic protection provides both overload and short-circuit sensing in a single device. Business Impact: This reduces nuisance trips, conductor damage, and unplanned downtime on critical loads like motors and conveyors. Application: Suitable for industrial control panels, machine enclosures, and power distribution blocks where dependable protection is essential. The 22 kAIC interrupt rating ensures the breaker can safely interrupt high fault currents without bus damage. Business Impact: This minimizes cascading failures and extends equipment life in plants with high short-circuit risk. Application: Useful in motor starters, feeders, and branch circuits fed from moderate to large power distribution panels. The 120/240 V two-pole design supports multi-wire branch circuits and common neutral configurations. Business Impact: It enables coordinated protection across related circuits while maintaining wiring simplicity and safety. Application: Widely used in industrial equipment, HVAC panels, and general-control panels. Plug-on mounting with fixed terminals simplifies installation and reduces field wiring variance. Business Impact: Faster commissioning, fewer wiring errors, and easier swaps during maintenance. Application: OEM controls and retrofit projects in manufacturing lines benefit from rapid, reliable panel assembly. UL Listed and CSA Certified with HACR rating provide regulatory confidence and broad applicability. Business Impact: Procurement becomes more straightforward, testing cycles shorten, and compliance risk decreases across multiple jurisdictions. Application: Ideal for panel builders, integrators, and service teams supporting HVAC, industrial machinery, and process equipment.

FAQs
QPHW2020 is designed for plug-on mounting with fixed terminals, making it straightforward to install in standard industrial control panels. Its two-pole, 120/240 V configuration fits most MCCs and distribution enclosures, and the 3 in x 3 in footprint supports compact spaces. Using the included wiring practices, you can reduce field wiring errors and commissioning time.
QPHW2020 delivers both thermal overload protection and short-circuit interruption with a 22 kAIC rating. The 20 A amperage rating suits motor starters and light-industry loads, while the thermal-magnetic trip curve minimizes nuisance trips during inrush. This combination improves uptime and protects conductors, motors, and control circuits in demanding environments.
Yes. The HACR-rated design is intended for HVAC equipment and other heating, ventilation, and air conditioning panels. UL Listed and CSA Certified, it meets typical regulatory requirements for commercial and industrial HVAC installations while maintaining reliable protection at 120/240 V.
QPHW2020 carries UL Listed and CSA Certified marks, and its HACR-rated performance aligns with common building and equipment standards. These certifications help simplify procurement, testing, and regulatory approvals in panel builds and machinery across multiple industries.
Use plug-on mounting and fixed terminals to minimize field wiring issues and torque variability. The compact 3x3 inch footprint, low 0.5 lb weight, and fixed terminals simplify rework in crowded panels, while the 20 A rating and 22 kAIC interrupt capacity provide robust protection against faults without over-sizing. Non-interchangeable option prevents incorrect replacements.
