FAQs
The CB174-10 is designed for 12–24V automotive systems and uses quick-connect terminals for rapid, secure wiring in standard automotive harnesses. It fits common Bussmann series protection schemes and can be integrated into fuse blocks or protected modules with minimal wiring changes, reducing installation time and miswiring risk. Always verify connector type and torque requirements per vehicle harness specifications.
The Type III trip curve provides a defined threshold for overcurrent events, enabling precise response to faults while avoiding trips for minor surge conditions typical in automotive loads. With a 10 A rating, it safeguards wiring and components, maintaining system integrity even during startup surges or transient faults common in lighting, accessories, and small motors.
Yes. The CB174-10 is well suited for auxiliary circuits, battery feeds, and lighting in 12–24V vehicle systems. Its 10 A rating, compact form factor, and quick-connect terminals make it ideal for space-constrained panels in dashboards, engine compartments, or protected modules, while providing reliable overcurrent protection.
CB174-10 is RoHS compliant, with the option to confirm additional approvals (such as CE or SIL) directly with the manufacturer. For traceability, use the UPC 051712593373 and catalog number CB174-10. Always verify current certifications with Eaton when specifying for regulated or OEM applications to ensure full regulatory alignment.
The CB174-10 delivers low maintenance due to solid solid-state-like protection characteristics and robust mechanical design suitable for automotive vibration environments.
