FAQs
To install CBC-25HB, connect the #10-32 TPI studs to the feed and protected load conductors using appropriate hardware and insulators. Secure the device in its designated enclosure or mounting bracket, ensure clean terminals, and verify the stud nuts are snug to prevent vibration-induced loosening. Always refer to Eaton's datasheet for torque guidance and verify market-specific approvals before field deployment.
CBC-25HB provides a 25 A amperage rating with a 1.5 kAIC interrupt rating at 14 Vdc. These specifications define the maximum fault current the breaker can safely interrupt and the continuous load it can protect, which is essential for sizing in automotive and light industrial circuits.
Yes. The CBC-25HB is designed for 14 Vdc automotive circuits and can be used in harness protection and compact control panels. Its 13.31 in length and 10-32 stud connection support integration into standard automotive wiring schemes, while the 1.5 kAIC interrupt rating provides a robust fault-clearing capability for protected loads.
Certification specifics are market dependent. Eaton designates compliances as information to be confirmed with the factory, and the official datasheet lists exact regulatory approvals. Always consult the CBC-25HB datasheet and local regulatory requirements to verify CE, UL, IP, SIL, or other certifications for your installation site.
CBC-25HB delivers consistent protection that reduces the risk of wiring damage and unexpected outages, lowering downtime and maintenance costs. Its reliable trip performance and standard connections simplify spares management and installation, contributing to improved overall equipment effectiveness (OEE) and a favorable return on investment over the device lifecycle.
