Eaton CBT-30M Automotive Circuit Breaker - Type II
Part Number: CBT-30M
Quick Summary
Automotive circuit breaker CBT-30M from Eaton protects critical vehicle and machine control circuits by reliably interrupting fault currents. For design teams facing nuisance trips and tight panel space, this compact device offers a plug‑in solution that simplifies enclosure layouts and maintenance. While RoHS compliance is documented, buyers often look for CE, IP, and SIL certifications; these items should be confirmed with the manufacturer for full compliance in automotive and industrial environments. Using this Eaton component supports uptime, safer service intervals, and consistent Bussmann-series compatibility across spares and replacements. That combination of protection, form factor, and supplier alignment makes it suitable for automotive OEM panels and light industrial control applications.
