FAQs
CBC-10HB uses a #10-32 TPI stud connection, so installers should secure the stud terminals to rated lugs or bus bars with the appropriate torque specified by Eaton. Ensure clearances around the unit for heat dissipation and vibration exposure in engine compartments. Verify panel space allows for its 13.31 in length and 9.63 in height footprint, and plan wiring routes to minimize wear or chafing.
A 1.5 kAIC interrupt rating defines the maximum fault current the breaker can interrupt safely. For automotive power feeds and accessory circuits, this rating provides meaningful protection against high‑energy faults typical in vehicle harnesses, reducing arc energy and limiting collateral damage to wiring, connectors, and adjacent components.
Yes. With a 14 Vdc nominal rating and a 10 A current rating, the CBC-10HB is well suited for protecting ECU power feeds and essential battery lines in 12–14 V automotive systems. The robust Type I construction and secure #10-32 stud connection help maintain reliable protection under engine‑bay vibration and temperature variation.
Compliance details are not listed in the provided data. It is important to contact Eaton to obtain the exact certifications applicable to your region (such as SIL, CE, IP ratings). Certification verification ensures the part meets your production and safety requirements before deployment in regulated applications or cross‑border programs.
The CBC-10HB reduces fuse replacements and prevents costly electrical faults by delivering rapid, reliable overcurrent protection. Its durable connection and rugged construction lower maintenance needs in high‑vibration environments. Over time, this translates to lower total cost of ownership, fewer warranty claims, and faster diagnostics during vehicle service and field upgrades.
