Eaton Specification Sheet - BK/CBC-30B
14 Vdc, 30 A rating and 1.5 kAIC interrupt rating translate into immediate fault isolation, reducing wiring damage and unscheduled downtime in automotive harnesses. For field teams, this means fewer reworks and faster service in fleet applications where reliability matters most. Compact footprint and heavy-duty design deliver installation flexibility in space-constrained enclosures. The dimensions 0.55 in L, 1.7 in W, and 1.27 in H, combined with a 0.5 lb weight, enable easy integration into vehicle dashboards and engine bays. Secure connection is provided by a #10-32 TPI stud, supporting robust mechanical mounting and vibration resistance. Packaging information—6 units per pack, with 100-unit packaging available for retail displays—supports both aftermarket stocking and OEM replenishment. Compatibility with the CBC-B family offers consistency with Eaton Bussmann protection products, reducing training and acceptance time for procurement teams. In application, this breaker is suitable for automotive circuits such as accessory loads and harness feeds, delivering predictably fast trips under fault conditions. Potential objections about certifications are addressed by referencing official Eaton specification sheets and the need to confirm CE/UL approvals with the manufacturer. Designed for field replaceability, compact size fits tight automotive enclosures, and compatible CBC-B accessories streamline servicing across fleets.
