Eaton CBC-8 automotive circuit breaker - 1.5 kAIC
Part Number: CBC-8
Quick Summary
The Eaton CBC-8 automotive circuit breaker protects 14 V automotive systems by interrupting faults. Engineers struggle with space constraints and unreliable protection in tight vehicle harnesses. Certification details are not published; contact factory for CE, IP ratings or SIL considerations for your application. In practice, automotive protection devices often pursue standard compliance per market, but specifics vary by end-use. This device's compatibility with standard #10-32 studs simplifies stocking and installation, while the 8 A rating provides targeted protection for accessory circuits. By selecting CBC-8, you gain predictable protection, easy field service, and reduced risk of electrical faults in critical vehicle systems. Engineers benefit from Type I characteristics, which provide predictable tripping behavior for automotive faults. With an all-in-one package, the CBC-8 reduces the time needed to spec, source, and install protective devices, improving uptime and maintenance planning.

Eaton Specification Sheet - CBC-8
Feature: The CBC-8 delivers a defined electrical rating of 14 Vdc, 8 A with an interrupt capacity of 1.5 kAIC, providing fast protection for automotive circuits. Business impact: This fast-acting protection minimizes voltage drop and downstream damage, reducing downtime and service costs. Application: Well-suited for auxiliary circuits, charging lines, and critical sensors in 14 V vehicle architectures. Feature: Terminal connection uses a standard #10-32 TPI stud, delivering a robust mechanical and electrical connection that resists vibration. Business impact: Fewer loose connections translate to stable resistance, fewer nuisance trips, and longer service intervals. Application: Ideal for integration into relay panels, fuse blocks, and harness junctions where field replacement is common. Feature: Compatible with common automotive protection workflows; the CBC-8's Type I designation and Bussmann series lineage offer predictable performance. Business impact: Aligns with established automotive protection strategies, simplifying training and procurement. Application: Suitable for integration in vehicle protection schemes where 14 V systems demand reliable circuit interruption. Feature: Physical footprint and documentation support installation in automotive service environments; dimensions are 14.75 in length, 9.25 in width, 7.5 in height, and weight 0.5 lb. Business impact: The sizeable but instrumented form factor provides robust insulation and clear terminal access, reducing installation time and miswiring risk. Application: Useful in onboard electronics enclosures, tool room displays, and service bays that rely on standardized, labeled components. Feature: Documentation and resources from Eaton — including brochures, catalogs, and the CBC-8 specification sheet — help verify compliance and compatibility. Business impact: Streamlined sourcing accelerates procurement cycles and improves change management. Application: Refer to the Eaton specification sheet and planograms for up-to-date installation guidance and cross-reference with other Bussmann series products.
