The QPHW2090 uses a two-pole, plug-on mounting arrangement that simplifies installation and speeds panel assembly, delivering immediate time savings on project timelines and reducing field wiring errors. Business impact: faster commissioning and lower labor costs. Application: panel manufacturers and field technicians benefit from a reliable, vibration-resistant connection with fixed terminals for consistent performance in harsh environments. The device provides 90 A nominal protection with a 22 kAIC interrupt rating, delivering robust short-circuit protection for motors and power distribution circuits, which translates into reduced equipment damage and downtime during fault events. In practice, this supports safer startups and longer equipment life in demanding manufacturing settings. The thermal-magnetic trip (T268) provides coordinated protection for both overload and short-circuit conditions, enabling precise selectivity in multi-circuit panel racks used in robotics and process control. The unit is HACR rated and CSA Certified UL Listed, ensuring HVAC and general industrial compliance while simplifying supplier audits and installation validations. Its compact footprint (3.1 in L x 2.1 in H x 3.5 in W) and light weight (0.6 lb) help maximize panel density and reduce enclosure costs, a meaningful advantage for budget-conscious automation projects.
