Eaton Specification Sheet - CB223-30
The CB223-30 uses a Type III ATC footprint, matching standard automotive fuse blocks and connectors. This compatibility reduces integration time, simplifies spares, and supports quicker field swaps in harness assemblies. ATC footprint compatibility also enables common tooling and service workflows for maintenance teams. Rated at 30 A and 24 V DC, the device provides precise protection for common automotive loads, helping prevent nuisance trips and minimizing fault-related downtime. This protection boundary supports reliable start-stop cycles and safer power distribution in critical circuits. Engineers can size the breaker with confidence for typical automotive accessories and controllers. The housing is UL-rated 94V-0 thermoplastic and RoHS compliant, delivering flame retardant performance and environmental responsibility. This reduces risk during manufacturing and in-dash installations where heat and vibration are factors. The combination supports safety certification workflows and supplier compliance programs. Its compact size—1.5 in long, 0.75 in wide, 0.25 in high—and light weight (approximately 0.02 lb) enables dense packaging and lighter harnessing. This helps achieve better overall vehicle efficiency and easier routing in tight electrical bays. You can deploy multiple protection points in a limited space without adding significant mass. The CB223-30 is offered with gold covers for Type I and silver covers for Type II and III, enabling visual differentiation and enclosure compatibility. This versatility supports standardized assemblies while preserving enclosure aesthetics and reliability. For retrofit projects, the cover options simplify stocking and replacement decisions. The Eaton Bussmann family alignment ensures consistency with existing catalogs and supply chains, improving procurement efficiency and stock management. The device is RoHS compliant and UL-rated, contributing to consistent regulatory compliance across automotive programs. The combination of footprint, rating, and compliance helps meet both design specs and manufacturing schedules.

FAQs
CB223-30 uses a Type III ATC footprint, matching standard automotive fuse blocks and connectors. It fits typical harness blocks and is compatible with the Eaton Bussmann automotive protection ecosystem, enabling quick field swaps and straightforward spares management in passenger cars, light trucks, and off-road applications.
CB223-30 provides a 30 A amperage rating at 24 V DC. It features a UL-rated 94V-0 thermoplastic housing and is RoHS compliant, supporting flame retardancy, environmental compliance, and safety certification workflows in automotive designs.
Yes. The UL 94V-0 housing and RoHS compliance contribute to safety and environmental resilience, while its compact, lightweight design (1.5 in L Ă— 0.75 in W Ă— 0.25 in H; ~0.02 lb) helps maintain vehicle reliability in space-constrained, vibration-prone environments.
CB223-30 employs a standard Type III ATC footprint, enabling plug-in replacement in compatible fuse blocks. Verify correct amperage rating for the load, ensure secure electrical connections, and align with enclosure covers (gold for Type I or silver for Type II/III) to maintain enclosure integrity during maintenance.
The device provides reliable protection with a compact footprint, reduces spare-part complexity, and simplifies procurement through compatibility with Eaton Bussmann catalogs. This translates to lower downtime, faster service, and smoother regulatory compliance across automotive programs, while preserving harness space and weight budgets.
