Two-pole CHF245 design with 10 kAIC interrupt rating provides rapid fault interruption, reducing conductor damage and arc flash risk across 120/240 V circuits. The thermal magnetic mechanism combines overcurrent protection with instantaneous magnetic trip during high fault currents, delivering dependable performance in both lighting and small motor applications. For panel builders and integrators, this means a clear, deterministic response that aligns with project safety plans and commissioning checklists. UL 489 certification and HACR rating underpin code-compliant operation for motor loads and general purpose circuits. In practice, you gain predictable trip characteristics during motor starting and inrush conditions, minimizing nuisance trips without compromising protection. The CHF245's verifiable qualification also simplifies procurement approvals and warranty claims in regulated environments. Compact dimensions and Type CH form factor support straightforward installation in crowded or retrofit panels. With a depth of 1.5 in, height of 2.6 in, width of 3.2 in, and a weight of 0.5 lb, the CHF245 preserves space for feeders and other devices while easing handling in field assembly. The built-in trip flag further reduces diagnostic time after a fault occurs. Compatibility with Type CH Loadcenters and common-trip operation with other CH breakers simplifies panel planning, stocking, and future expansion. Engineers appreciate the standardized mounting and wiring footprint, which translates to lower commissioning risk and faster changeouts during maintenance windows. The CHF245 also supports 120/240 V dual-voltage systems, making it a versatile choice for mixed-voltage installations. Comprehensive documentation, including the Eaton Specification Sheet and warranty guidance, is readily accessible to support procurement and maintenance planning. The official UL 489 datasheet guides installation and code compliance, while the warranty information helps quantify total cost of ownership over equipment life. This combination of documentation and performance translates into reduced risk, reliable protection, and predictable ROI for projects.
