Eaton Specification Sheet - CBS-20
The CBS-20 delivers a 20 A amperage rating for automotive circuits, enabling precise overcurrent protection that guards harnesses and loads from wiring damage. This targeted protection reduces the likelihood of costly automotive electrical failures and unexpected downtime. With a compact footprint of 4.67 in long, 1.84 in wide, and 1.6 in high, the device fits crowded fuse blocks and tight dash panels. Installation becomes quicker and more reliable, as fewer enclosures require oversized protection devices. RoHS compliance supports regulatory alignment and sustainable sourcing, simplifying audits and supplier qualification. It minimizes supply chain risk by standardizing a widely accepted environmental standard across automotive programs. Traceability is streamlined by catalog data and UPC 051712139571, aiding BOM management and field replacements. This level of inventory control accelerates procurement and reduces misorders. Compatibility with Eaton Bussmann series protection products and planograms aids seamless integration into existing protection schemes. The CBS-20 aligns with Bussmann catalogs and common automotive fuse blocks, reducing retraining and enabling fast stock replenishment. Real-world insights show that reliable 20 A protection improves uptime under temperature cycling and vibration, with fewer nuisance trips and simpler warranty support when using a proven Bussmann series option.

FAQs
CBS-20 should be mounted in an appropriately rated enclosure within the vehicle’s harness or fuse block. Ensure space for the 4.67 in length and 1.84 in width, provide secure connections to the protected circuit, avoid over-tightening connectors, and follow Eaton's specification sheet for torque and mounting recommendations to prevent vibration-induced loosening.
The 20 A rating provides a balance between protecting wiring insulation and allowing normal startup surges in typical automotive loads. It minimizes nuisance trips during transient inrush events while still interrupting faults quickly, reducing damage to wiring harnesses and components and lowering downtime and repair costs.
Yes, CBS-20 is RoHS compliant, aligning with environmental and regulatory expectations for automotive components.
