Special features
120/208/240 Vac shunt trip
With a 20 A rating and a 22 kAIC interrupt capacity, the QPHW2020S provides precise overload protection for motor feeders and control circuits. This minimizes nuisance trips and speeds fault isolation, reducing downtime in automation lines such as assembly, packaging, and material handling. The two-pole, thermal-magnetic design delivers reliable protection without sacrificing control performance. Plug-on mounting simplifies installation and panel integration, reducing wiring complexity and field terminations. Compatibility with standard panels and the Eaton Quicklag family shortens commissioning times and lowers labor costs, especially during retrofit projects. The built-in shunt trip supports 120-240 V remote actuation for emergency stops and safety interlocks. This capability improves safety compliance in critical lines such as conveyors and robotic cells, enabling rapid de-energization during faults. HACR-rated performance ensures suitability for HVAC controls, simplifying design and reducing separate protection devices. UL Listed and CSA Certified with a one-year warranty provide regulatory assurance and lifecycle predictability. The rugged construction, lightweight footprint, and 120/208/240 V shunt-trip option support scalable protection across multiple lines, while the 22 kAIC rating aligns with common industrial power distributions.
