Eaton CHB315 CH thermal magnetic circuit breaker - 10 kAIC
Part Number: CHB315
Quick Summary
CHB315 CH thermal magnetic circuit breaker protects electrical panels by interrupting faults in 240 V distribution systems. Engineers often face nuisance trips and inconsistent protection when mismatched breakers are used in CH Loadcenters. UL 489 certification is standard, and Eaton's documentation notes compatibility with CH family; additional certifications may apply per installation. With this model, you gain reliable fault isolation, reduced downtime, and predictable trip performance across your critical circuits. Installing compatible devices simplifies stocking, accelerates commissioning, and improves total cost of ownership for commercial and light industrial panels. This combination of ratings and form factor supports safer, compliant panel protection for 240 V systems.

Feature → Business Impact → Application: The CHB315 employs a thermal-magnetic trip mechanism, delivering precise coordination between overload protection and short-circuit interruption, which reduces nuisance trips and extends equipment life in CH Loadcenters used in 240 V commercial buildings and light industrial facilities. This translates to lower maintenance costs and minimized downtime when protecting feeder circuits and downstream equipment. Feature → Business Impact → Application: Three-pole construction supports true three-phase protection for 240 V panels, streamlining wiring schemes with #14-8 AWG conductors and enabling consistent protection across all phases in CH Loadcenters. This improves panel reliability in manufacturing lines and data centers with distributed loads. Feature → Business Impact → Application: 10 kAIC interrupt rating provides robust fault handling for high-energy events, helping meet industry standards and reduce service interruptions in critical applications. Feature → Business Impact → Application: Compact dimensions and weight (5.8 in L, 2.1 in H, 3.6 in W; 0.85 lb) offer installation flexibility in crowded distribution cabinets and retrofit projects, supporting faster commissioning and reduced enclosure modifications. Feature → Business Impact → Application: UL 489 listing and compatibility with CH Loadcenters simplify procurement and compliance, lowering total cost of ownership while delivering predictable performance for 15 A, 240 V circuits in both new builds and upgrades. Feature → Business Impact → Application: Wire size compatibility (#14-8 AWG) ensures standard copper or aluminum wiring practices, reducing field labor and potential mis-wiring risks during terminations in panel boards and switchgear enclosures.

FAQs
The CHB315 is a three-pole, 15 A device designed for CH Loadcenters operating at 240 V. Use #14-8 AWG conductors, mount in standard CH slots, and follow torque specifications from Eaton. Ensure UL 489 listing is recognized for the panel and verify enclosure clearance to maintain proper cooling and safe operation. Proper compatibility with the CH family minimizes mis-wiring and eases service.
The CHB315 combines thermal overload protection with magnetic short-circuit protection, allowing selective tripping and fast fault clearance. This reduces nuisance trips on lightly loaded circuits while maintaining rapid interruption during high-energy faults, which is essential for protecting conductors sized #14-8 AWG and connected CH Loadcenters in demanding environments.
Yes. The CHB315 is rated at 240 V and configured as a three-pole breaker for true three-phase protection, with a 15 A rating and a 10 kAIC interrupt capacity. It is designed for use with CH Loadcenters, making it a suitable choice for industrial and commercial panels requiring reliable 240 V protection and standard wiring.
CHB315 is UL 489 listed, aligning with national electrical safety standards for circuit protection. Eaton specifies CH Loadcenter compatibility and recommends confirming any additional certifications applicable to your country or installation. This certification basis supports compliance in regulated environments and helps streamline inspector acceptance during panel installations.
Using CHB315 can reduce downtime through reliable thermal-magnetic protection and predictable tripping behavior, lowering maintenance costs. Its compatibility with CH Loadcenters simplifies stocking and spares inventory, while the limited lifetime warranty provides long-term value. The combination of robust protection and easy service can shorten mean time to repair (MTTR) and extend panel lifecycle.
