Eaton CB123-30B Automotive Circuit Breaker - 1.5 kAIC

27 Vdc, 30 A rating provides reliable protection for DC circuits in automotive power distribution. This device interrupts a fault quickly to limit arc energy and prevent wire insulation damage, while maintaining safe shut-off under load. Business impact: improved equipment uptime and reduced battery drain during fault events. Application: power distribution blocks, ECU power rails, and accessory controllers in automotive or off‑highway applications. With an interrupt rating of 1.5 kAIC at 12 Vdc and a Type III series construction, CB123-30B withstands high-current faults and vibration without nuisance tripping. Business impact: fewer false trips that interrupt production lines or diagnostic work, and better protection for sensitive sensors. Application: heavy-duty control circuits, motor-starting circuits, and rugged harnesses in commercial vehicles. Connection uses #10-32 TPI studs, enabling direct mounting to standard terminals and ease of replacement in field installations. This reduces wiring complexity and enables reliable harness integration. Business impact: lower installation time and fewer connection failures, translating to lower maintenance costs. Application: inline power feeds and distribution close to controllers in dashboards, engine bays, and chassis installations. RoHS compliance supports regulatory alignment in markets with restricted substances; while CE certification specifics should be confirmed with Eaton for certain regions, the RoHS statement helps streamline approvals. Business impact: faster time-to-market and simplified supplier qualification. Application: automotive electronics supply chains requiring compliant protection devices. Rugged design and Bussmann lineage provide predictable performance across temperature and vibration in automotive environments, with a strong protection margin for power rails during transients. Application: rugged vehicle electronics and high-current protection.
