Special features
50° C Calibration
40 A amperage rating → Business impact: protects control circuits and modest motor loads with precise trip coordination, reducing nuisance trips and extending equipment life. Application: ideal for panel boards in machine controls and distribution blocks where reliable, selective protection keeps critical processes running and simplifies coordination with upstream protective devices. In practice, this rating helps engineers avoid oversizing protections that add cost and heat. 22 kAIC interrupt rating → Business impact: withstands high fault currents without catastrophic trips, lowering damage risk to conductors, transformers, and connected equipment. Application: feeders and line-side protection in harsh industrial environments where fault currents can spike unexpectedly. This capability also supports safer maintenance windows by limiting arc energy exposure. 50°C calibration → Business impact: maintains accurate trip thresholds even in elevated ambient temperatures, preventing under- or over-tripping as environments heat up. Application: factory floors, warehouses, and process lines where heat is a normal condition. This specification helps facilities stay compliant with temperature derating guidelines while preserving protection reliability. Plug-on mounting and plug-on terminals → Business impact: speeds installation and retrofit projects, reducing wiring errors and labor costs. Application: new control panel builds and replacements in existing assemblies where a compact, single-pole breaker simplifies layout. The non-interchangeable option clarifies stocking and replacement strategies, minimizing misfits during maintenance. UL Listed, CSA Certified with HACR rating → Business impact: delivers code-compliant, proven protection with vendor-backed reliability, supporting long-term TCO. Application: industrial facilities seeking predictable maintenance budgets and clear supplier accountability. 1-year warranty → Business impact: reduces risk during initial operation and early-life support, improving overall project ROI. Application: all installations requiring documented vendor support and predictable service life.

FAQs
Install the QPHW1040V using its plug-on terminals in a single-pole configuration for 120/240 V circuits. Ensure correct alignment with panel bus bars, tighten terminals to spec, and verify 40 A rating aligns with the protected load. Its plug-on design reduces wiring time and simplifies retrofits in existing enclosures.
The breaker features a 22 kAIC interrupt rating, allowing it to safely interrupt high fault currents without tripping other devices. This capability protects conductors and equipment from damaging arc energy and supports safer maintenance while maintaining system uptime in demanding industrial sites.
Yes. The unit is UL Listed and CSA Certified and carries HACR rating, meeting North American electrical codes for commercial and industrial installations. These certifications verify reliability, safety, and performance under typical operating conditions.
Ideal for control panels, machine control circuits, and industrial feeders that require reliable 40 A protection at 120/240 V. It’s well-suited for panel boards and distribution blocks in manufacturing environments where quick, selective trips minimize downtime and support scalable panel design.
A 1-year warranty accompanies the unit, offering protection during early operation. Its plug-on design reduces installation labor, and its high interrupt rating helps prevent equipment damage, contributing to lower total cost of ownership and improved production reliability over the device lifecycle.
