Eaton Specification Sheet - CL230
Feature → Business Impact → Application: The CL230 is a 1-Inch classified replacement breaker that fits Type CH load centers, reducing panel space constraints while maintaining code-compliant protection. Benefit: Simplifies retrofits and minimizes panel rework, improving project timelines for residential and light commercial installations. Application: Ideal for upgrading legacy systems where a like-for-like form factor is required without rewiring the panel. Feature → Business Impact → Application: 30 A, 120/240 V, two-pole operation with common trip ensures synchronized shutoff across circuits, enhancing safety and ease of maintenance. Benefit: Improves fault isolation, reduces nuisance trips, and supports tighter coordination within multi-breaker assemblies. Application: Suitable for multi-circuit protection in modernized panels that demand reliable coordination. Feature → Business Impact → Application: 10 kAIC interrupt rating provides high fault current withstand, protecting conductors and devices from damage. Benefit: Higher system resilience in commercial spaces with elevated fault levels. Application: Critical for electrical distribution where short-circuit withstand matters. Feature → Business Impact → Application: Copper/Aluminum wire compatibility (#14-4 AWG) broadens installation options and supplier flexibility. Benefit: Cost savings from versatile wiring choices and easier splicing. Application: Streamlines field wiring in mixed-material installations. Feature → Business Impact → Application: UL 489 certification and documented compatibility with CH load centers. Benefit: Compliance assurance and easier regulatory auditing. Application: Required in most jurisdictions for low-voltage protection in residential and light commercial panels. Feature → Business Impact → Application: Requires two 1-inch spaces in the panel. Benefit: Clear space planning simplifies panel layout and reduces installation errors. Application: Suitable for standard CH load centers needing precise fitment. Feature → Business Impact → Application: Limited lifetime warranty (residential) with 1-year commercial coverage. Benefit: Long-term protection and predictable maintenance budgeting. Application: Procurement planning for facilities with mixed-use panels and service longevity goals.
