Eaton Specification Sheet - CBC-35
The CBC-35 is rated for 14 Vdc operation, delivering controlled current interruption to protect battery lines and accessory circuits; this reduces exposure to arc faults and wiring damage in cramped engine bays. The 35 A amperage rating matches common automotive loads, enabling precise protection without nuisance tripping, which improves system reliability and reduces downtime. With an interrupt rating of 1.5 kAIC, the device tolerates high fault currents and minimizes collateral damage to harnesses and wiring assemblies, supporting longer component life and lower maintenance costs. The #10-32 TPI stud connection simplifies field installation and integration into standard automotive panels, enabling faster service and easier retrofits in fleet environments. Type I trip characteristics offer predictable response in typical automotive fault scenarios, aiding validation against OEM protection requirements. Documentation and compatibility with the CBC family help fleet managers maintain consistent protection strategies across vehicles and modules.
