Two-pole plug-on mounting enables fast, tool-light installation in crowded panel spaces, reducing configuration time during builds. This streamlined approach minimizes field wiring errors and accelerates commissioning, delivering measurable labor savings and quicker time-to-value for automated lines. Compatibility with standard DIN rails and the Eaton Quicklag family ensures retrofits into existing control architectures without sacrificing density. The thermal-magnetic trip combines precise overload protection with rapid magnetic disconnection on short circuits, preserving motor starter life. That dual protection reduces nuisance trips, limits arc-flash exposure, and safeguards sensors in demanding production environments. Designed for industrial circuits such as motor feeders and machine control panels, it supports scalable protection in evolving automation architectures. With a 22 kAIC interrupt rating, the QPHW2020H withstands high fault currents to shield upstream devices and downstream schemes. This capability improves system reliability during surge events and simplifies protection coordination with adjacent breakers and switchgear. It is well suited for switchgear, panel boards, data centers, and environments where robust interruption capacity matters. Operating at 240 V and 20 A aligns with common industrial power distribution and motor circuits, enabling straightforward replacement in many panels. Fixed terminals and rugged construction minimize connection failures, while plug-on mounting supports quick field service. This combination reduces downtime during maintenance and supports reliable deployment across mixed automation platforms. UL Listed, CSA Certified, and HACR rated, the QPHW2020H meets essential regional safety and energy-efficiency standards for industrial equipment. These certifications simplify procurement, streamline regulatory filings, and enable safer operation in HVAC, conveyor, and automation applications. Together, they support supplier qualification, compliance auditing, and scalable growth across facilities requiring robust protection.
