Eaton Specification Sheet - CHQ215CS
Compatibility with Eaton Type CH Loadcenters reduces integration risk and ensures proper fit in two-space clamshell packs, enabling faster replacements in field installations and retrofits. The 120/240 V rating and 10 kAIC interrupt capability translate to safer, more reliable protection for multiwire branch circuits, supporting compliance with NEC requirements and minimizing arc exposure in typical industrial and commercial applications. The CHQ215CS comes in a clamshell pack, which protects against shipping damage and simplifies handling in distribution centers, field warehouses, and onsite installations. As a classified CHQ 3/4-Inch replacement, it enables seamless swaps for Square D QO breakers, helping maintenance teams consolidate parts and reduce stocking costs. Its two-pole design, common-trip feature, and conductor sizing (Cu/Al) support robust multi-circuit protection in panelboards and load centers while maintaining space efficiency. Field technicians benefit from clear labeling and Eaton compatibility, reducing commissioning time and post-installation adjustments. Overall, adopting this model supports lifecycle cost reductions through standardized components across projects and facilities.

FAQs
The CHQ215CS is designed for Eaton Type CH Loadcenters and is intended as a classified replacement within these panels. It fits the CH space configuration and supports two-pole operation for standard branch circuits in residential and light commercial installations, streamlining retrofits and new builds alike.
CHQ215CS is a 3/4-inch, two-pole thermal magnetic circuit breaker rated for 120/240 V with a 10 kAIC interrupt rating. It is listed as UL 489 and provides a 15 A current rating in a clamshell package, designed for CH Loadcenters and compatible with copper or aluminum conductors as specified (2) #14-10 AWG Cu/Al and (1) #14-8 AWG.
Choosing CHQ215CS provides a reliable, code-compliant replacement that matches the existing Type CH architecture. It reduces downtime by offering a known fit, minimizes stocking complexity with standard CH components, and ensures common-trip protection across two poles, which is critical for maintaining safe, synchronized tripping in multi-circuit panels.
CHQ215CS carries UL 489 certification, confirming safe performance for circuit protection applications. While UL 489 is specified, CE marking or IP ratings are not indicated for this model. Users should verify local compliance requirements, but UL 489 is widely recognized for residential and light commercial panel protection.
Installation requires two 3/4-inch spaces within CH Loadcenters and uses a clamshell pack for transport and handling. It supports a two-pole configuration with 120/240 V operation and is compatible with (2) #14-10 AWG Cu/Al and (1) #14-8 AWG conductors. Proper torque and mounting in a CH panel ensure reliable protection and easy future replacement if needed.
