FAQs
Install the CBC-10B by securing the device to a compatible mounting point using the #10-32 TPI stud. Ensure the circuit aligns with a 14 Vdc supply and that the wiring gauge and connectors meet the vehicle’s harness specifications. Verify tight torque on the stud to maintain reliable contact and minimize resistance, especially in vibration-prone automotive environments.
CBC-10B provides 14 Vdc operation, a 10 A current rating, and a 1.5 kAIC interrupt rating. This means the device will reliably carry up to 10 A under normal operation and will interrupt fault currents up to 1.5 kA at 14 Vdc, helping prevent wiring damage and reducing the risk of thermal events in vehicle electrical systems.
Yes, the CBC-10B is designed for automotive use with a rugged construction suitable for vibration and thermal cycling typical in vehicles. Its compatibility with the CBC-B family makes it a scalable choice for fleet applications where consistent protection across multiple vehicles is needed, improving maintenance predictability and part standardization.
Compliance for CBC-10B is listed as contact factory, so verify regional regulatory requirements with Eaton before deployment. While the CBC-B family is designed to meet common automotive protection standards, exact certifications may vary by market, and the datasheet or spec sheet should be consulted for the latest validated declarations.
The CBC-10B delivers reliable overcurrent protection with quick fault isolation, reducing downtime and preventing costly electrical damage. Its field replaceable nature, compatibility with CBC-B modules, and straightforward installation contribute to lower maintenance costs, fewer warranty claims, and faster service cycles in fleet or OEM installations.
