Eaton CHF325SW circuit breaker - 10 kAIC UL 489

Thermal magnetic trip technology provides precise, fast protection for 25 A circuits while handling normal inrush in motor loads and lighting. The CHF325SW leverages a three-pole, 120/240 V design with a 10 kAIC interrupt rating, ensuring rapid fault clearance and reduced downstream damage. This device supports a common-trip across all poles and includes a switching neutral, which helps maintain safe operation in multi-wire branch circuits. For engineers, the combination of instantaneous magnetic clearance and time-delayed thermal protection delivers selective coordination with upstream protective devices, minimizing nuisance trips in complex panels. The Type CHF plug-on form factor also eases panel space planning and retrofit scenarios. Plug-on mounting streamlines installation by snapping directly onto Type CH backplanes, eliminating several field wiring steps and reducing the risk of miswiring during commissioning. The CHF325SW is designed for Type CH Loadcenters, enabling quick replacement of legacy breakers without disturbing adjacent circuits. With a universal neutral handling approach, switching neutral is preserved even when the breaker is tripped, enhancing fault visibility and safety. The unit’s rugged construction supports consistent performance in industrial environments, while the compact dimensions (3.5 in depth, 3.25 in height, 2.25 in width) help maximize panel density. This translates to faster changeouts and lower labor costs in both retrofit and new-build projects. Electrical compatibility and compliance are clear value drivers. Wire connections accept #14-6 AWG Cu/Al, covering most standard branch-circuit runs. The CHF325SW carries HACR compliance and UL Listed UL 489, providing confidence for HVAC equipment and general purpose panels. This certification footprint reduces supplier risk for regulated installations and supports easier procurement in regulated environments. The device's three-pole architecture and common trip enable reliable coordination with other CH family breakers, improving system reliability and uptime in critical processes. Long-term, the limited lifetime warranty offers financial protection against field failures and support costs. Together, these features make the CHF325SW a practical choice for controlled protection in Type CH Loadcenter environments, delivering predictable performance with a clear total cost of ownership advantage.
