Eaton Specification Sheet - CB223-25
Type III ATC footprint provides universal compatibility with standard automotive fuse blocks, reducing integration risk and simplifying spares holding. Business impact: faster installation and lower field rework. Application: fits in compact control enclosures where space is at a premium. The 25 A at 24 VDC rating delivers solid overload protection for high-current DC circuits, minimizing fuse replacements and boosting system reliability in power distribution networks. Application: automotive electrical harnesses and DC distribution modules. UL 94V-0 housing offers flame retardant safety, supporting safer engine compartments and meeting stringent enclosure standards. Business impact: reduced fire risk and improved safety compliance. RoHS compliant design ensures environmental responsibility, easing procurement across global supply chains. Application: regulated industries with strict material restrictions. The CB223-25’s compact form factor (1.5 in L × 0.75 in W × 0.25 in H) enables high-density panel layouts, lowering enclosure size and cooling requirements. Business impact: lower total cost of ownership and simpler integration in tight automotive dashboards and control blocks. Aspect: gold or silver metal covers (types I–III) provide protective finishes that align with existing hardware aesthetics and protection levels. Application: retrofit scenarios and modular power blocks where cover variants are preferred. The device ships as a single unit, streamlining stocking and installation workflows. Business impact: procurement simplicity and predictable lead times for maintenance and repair.

FAQs
Yes. CB223-25 uses a Type III ATC footprint, the same standard found in many automotive fuse blocks. This compatibility supports quick drop-in installation in existing DC power distribution layouts, minimizing panel redesign and wiring changes while maintaining reliable overload protection.
CB223-25 is rated for 25 A at 24 V DC. It features a UL-rated 94V-0 thermoplastic housing for safety and flame retardancy, and it is RoHS compliant to meet environmental and regulatory requirements. The compact dimensions are 1.5 in length, 0.75 in width, and 0.25 in height.
This device is ideal for automotive DC power distribution, including engine compartments, vehicle electrical harnesses, EV subsystems, and compact control panels. Its small footprint and robust protection make it suitable for both new builds and space-constrained retrofits where reliable DC circuit protection is critical.
CB223-25 carries UL-rated 94V-0 housing, indicating flame retardant performance and safety compliance, and RoHS compliance for restricted hazardous substances. These certifications help ensure regulatory alignment in automotive and industrial applications and support procurement with standard compliance requirements.
Plan for a Type III ATC socket, given the footprint, and account for the device’s 1.5 in length, 0.75 in width, and 0.25 in height in enclosure layouts. Use appropriate DC wiring up to the rated current, and ensure secure connections to prevent arcing. The unit ships as a single piece for straightforward stocking and installation.
