Eaton Specification Sheet - CBP-25BA
Compact form factor with a 2 in length, 1.3 in width, and 1.38 in height, plus a #10-32 TPI stud connection enables dense packaging and straightforward installation in crowded automotive harnesses. Business impact: space savings, faster assembly, and reduced wiring complexity, improving overall assembly time and reducing labor costs. Application: electrical protection right at the harness entry point in compact vehicle control panels and mobile equipment. 25 A rating at 14 Vdc with 1.5 kAIC interrupt capacity provides reliable protection for moderate automotive loads while limiting nuisance trips during normal operation. This translates to higher system uptime and lower risk of component damage under fault conditions. Application: infotainment, sensor arrays, and power distribution in light vehicles. Type I trip characteristics offer predictable protection behavior under automotive fault scenarios, supporting consistent maintenance planning and easier troubleshooting. Business impact: deterministic response improves diagnostic workflows and reduces warranty claims. RoHS compliant status ensures regulatory alignment across markets; consult the factory for additional certifications if required. Application: global OE programs and aftermarket deployments. Robust connection capability with a #10-32 TPI stud supports vibration resistance and durable terminations in automotive environments. Business impact: fewer connection failures and longer mean time between maintenance actions. Documentation and availability: the CBP-25BA is supported by Eaton catalogs, specification sheets, and planograms, enabling seamless procurement and engineering alignment. Application: design validation and supplier-ready documentation for automotive programs.

FAQs
CBP-25BA is designed for the rugged demands of vehicle wiring with a #10-32 TPI stud connection. Its 2 inch length and compact footprint simplify mounting in tight electrical bays, while the stud-based connection provides a robust, vibration-resistant interface. Ensure mounting location allows short, direct routing to minimize harness length and potential EMI. Use appropriate locking nuts and torque per vehicle spec to maintain secure, vibration-tolerant terminations.
CBP-25BA provides a 25 A amperage rating with a 14 Vdc operating voltage and a 1.5 kAIC interrupt rating. This combination supports protection for typical automotive loads without nuisance trips under normal operation while delivering rapid fault isolation during short circuits. The 14 Vdc rating aligns with standard vehicle electrical systems, ensuring compatibility across many automotive platforms.
Yes, CBP-25BA is intended for automotive use with a compact, high-strength connection and RoHS compliance. Verify compatibility with your vehicle’s battery voltage, system load, and mounting environment. Confirm the 2 in by 1.3 in by 1.38 in footprint fits your enclosure and that the #10-32 stud connection is suitable for the harness connector hardware used in your application.
CBP-25BA is RoHS compliant as documented by Eaton. For additional regulatory or industry certifications beyond RoHS, contact Eaton to confirm availability for your specific market or program. Always consult the official Eaton specification sheets and catalogs for the most up-to-date certification information and approved-use cases.
The CBP-25BA’s compact form factor, reliable 25 A protection, and 1.5 kAIC interrupt rating reduce downtime from electrical faults in automotive and mobile equipment. Its robust #10-32 stud connection minimizes vibration-related failures, lowering maintenance frequency. Coupled with RoHS compliance and Eaton documentation, it supports faster design validation, fewer field failures, and lower total cost of ownership over the vehicle’s service life.
