Thermal magnetic trip mechanism is designed to provide both instantaneous magnetic fault interruption and delayed thermal protection, reducing nuisance trips while maintaining selective coordination in feeders and branch circuits. This translates to fewer unexpected outages and quicker fault isolation in commercial panels, improving overall system reliability for CH-series installations. The 45 A, 120/240 V, 2-pole design supports common branch-circuit and lighting controls, enabling straightforward replacement in standard CH panels and ensuring consistent protection across circuits. With a 10 kAIC short-circuit rating, the CHF245CS withstands high fault currents, enhancing safety and compliance in service entrances and distribution panels while protecting valuable equipment. The unit’s clamshell packaging and CH-type compatibility streamline stocking, procurement, and field swaps, reducing downtime during maintenance and retrofits. Warranty and support from Eaton add to long-term value, lowering total cost of ownership for facilities managers and contractors working in industrial environments.
