Yes. CBC-30 uses a #10-32 TPI stud for secure electrical connection, enabling straightforward mounting in automotive harnesses and panels. The compact dimensions (1.25 in L, 1.25 in H, 0.75 in W) help fit into tight passenger-compartment or under-hood spaces while maintaining robust contact. Ensure stud torque and connector integrity per application standards.
CBC-30 is rated for 14 Vdc, 30 A with an interrupt rating of 1.5 kAIC. It features a Type I trip characteristic and a 10-32 TPI stud connection. These specs support reliable protection for automotive circuits against overcurrent faults while accommodating typical vehicle electrical loads and fault currents.
CBC-30 provides essential overcurrent protection for automotive harnesses at 14 Vdc, a common standard in many 12–14 V systems. For EV or high-voltage hybrids, verify voltage compatibility and any regulatory requirements with Eaton; consider product variants specifically rated for higher system voltages and different fault-current profiles.
The data sheet lists compliances as 'Contact factory,' so regional or application-specific certifications should be confirmed with Eaton. For CE, IP, or SIL applicability, coordinate with the manufacturer to ensure the CBC-30 meets your automotive or industrial regulatory requirements before deployment.
By delivering predictable trip behavior and robust fault protection, CBC-30 helps reduce unexpected downtime and protect valuable ECU and sensor circuits. Its compact form factor simplifies installation, while availability of datasheets and catalogs speeds procurement and spares planning. Regular inspections of stud connections and enclosure seals will maintain reliability in harsh automotive environments.
