Feature → Business Impact → Application: Classified 3/4-Inch replacement format fits CH Loadcenters and serves as a practical retrofit for Square D QO breakers, enabling code-compliant upgrades without panel replacement. Benefit: simplifies upgrades, reduces field install time, and minimizes panel disruption in both new construction and retrofit projects. Application: Ideal for residential, light commercial, and control-panel retrofits requiring a compact, classified solution. Feature → Business Impact → Application: Two-pole design with a common trip ensures simultaneous protection of paired circuits, reducing nuisance trips and protecting multi-wire branch circuits. Benefit: improves safety, streamlines wiring, and simplifies troubleshooting in shared-neutral configurations. Application: Suitable for CH Loadcenters and 2-pole circuit protection in 120/240 V systems. Feature → Business Impact → Application: 15 A rating with a 10 kAIC interrupt capability provides robust fault protection for typical lighting and receptacle circuits while tolerating high fault currents. Benefit: protects equipment and reduces downstream damage; supports code-compliant protection. Application: Used on lighting, receptacle, and small appliance circuits in both residential and light commercial panels. Feature → Business Impact → Application: Wire-size compatibility (two #14-10 Cu/Al, one #14-8) and two-space footprint simplify installation and maintain conductors within panel manufacturer guidelines. Benefit: ensures secure terminations, minimizes wiring errors, and supports reliable long-term operation. Application: Fits CH Loadcenters and retrofits requiring precise conductor sizing. Feature → Business Impact → Application: Catalog notes indicate it is a replacement for Square D Type QO Breakers, with two 3/4-inch spaces required. Benefit: broadens compatibility, reduces inventory needs, and speeds up retrofits. Application: For legacy QO-based installations migrating to Eaton CH platforms. Feature → Business Impact → Application: UL 489 certification and CHQ load-center compatibility provide compliance confidence and streamlined procurement. Benefit: enhances electrical-safety compliance and procurement efficiency. Application: Essential for regulated environments and new-builds requiring certified, compatible components.

FAQs
CHQ215 is designed as a classified replacement for Eaton Type CH Loadcenters and can replace older Square D QO breakers. It is a two-pole, 15 A device that requires two 3/4-inch spaces in the panel and features a common trip for paired circuits, aiding retrofits and panel organization without changing the enclosure.
CHQ215 provides 15 A protection with a 120/240 V rating and a 10 kAIC interrupt capability. It is a two-pole CH series breaker with a common trip, designed for CH Loadcenters, and accepts wire sizes of (2) #14-10 AWG Cu/Al and (1) #14-8 AWG per the installation guide.
Choosing CHQ215 ensures UL 489 listed performance and guaranteed compatibility with Eaton CH Loadcenters, as well as classified replacement status for QO-style panels. This reduces project risk, ensures code compliance, and simplifies procurement by aligning with the CH family’s mounting and trip characteristics.
Installers should observe the requirement to occupy two 3/4-inch spaces in the panel. Wire terminations use (2) #14-10 AWG Cu/Al and (1) #14-8 AWG. The device is intended for Type CH Loadcenters and should be installed with a common-trip pairing for dual-circuit protection, following local codes and NEC guidelines.
CHQ215 carries a limited lifetime warranty for residential use and a 1-year warranty for commercial installations. Eaton provides product datasheets and specification sheets to assist with design and installation, and support is available for compatibility inquiries, replacement parts, and ensuring proper integration with CH Loadcenters.
