Eaton Specification Sheet - CBC-10
Feature: 14 Vdc operation and 10 A rating enable reliable protection for automotive power distribution while minimizing voltage drop in critical circuits. Business Impact: This combination reduces the risk of nuisance trips during load transients and extends component life by preventing overcurrent damage. Application: Suited for vehicle harnesses, battery feeds, and auxiliary power circuits where space is constrained but protection is non-negotiable. Paragraph 2: Feature: 1.5 kAIC interrupt rating ensures safe disconnection of high-energy faults without collateral damage to wiring or downstream devices. Business Impact: Dramatically lowers repair costs after a fault, supports compliance with automotive protection design practices, and enhances fleet reliability. Application: Protects main and branch circuits in engine bays, instrument clusters, and power distribution modules subject to short-circuit events. Paragraph 3: Feature: Type I construction and secure #10-32 TPI stud connections offer reliable mounting with low contact resistance. Business Impact: Easier installation and reduced thermal hotspots translate to longer-life protection in harsh automotive environments. Application: Ideal for engine compartments and protected enclosures with tight spaces. Paragraph 4: Feature: Compact physical footprint (14.75 in L × 9.25 in W × 7.5 in H) with 0.5 lb weight aids enclosure planning and retrofits. Business Impact: Simplifies OEM packaging and aftermarket upgrades by fitting existing housings and minimizing added bulk. Application: Used in power distribution modules and portable power systems where space is a constraint. Paragraph 5: Feature: Availability via Eaton catalogs and downloadable datasheets (CBC-10) supports fast evaluation and sourcing. Business Impact: Reduces time-to-quote and accelerates procurement cycles across manufacturing and fleet maintenance. Application: Helpful for engineering teams conducting standard part checks and BOM verification.
