FAQs
Yes. CB185P-80 is designed for panel mounting and is well suited for compact automotive control panels and enclosure installations. Its 1.9 inch length, 2.1 inch width, and 2.9 inch height allow installation in limited spaces while providing reliable 48 Vdc protection with a switchable mechanism for safe maintenance.
CB185P-80 provides an 80 A amperage rating, a 3 kAIC interrupt rating, and a 48 Vdc voltage rating. Together these specs enable effective protection for medium to high-current automotive circuits, delivering rapid fault interruption to prevent wiring damage and component failure in demanding vehicle and equipment environments.
The device is ideal for automotive power distribution, battery management, and motor control circuits operating at 48 Vdc. Its panel-mount design and switchable feature make it suitable for control panels in vehicles and industrial equipment, where reliable protection and easy servicing are critical to uptime and safety.
CB185P-80 is RoHS compliant, supporting environmental and regulatory requirements in modern manufacturing. For customers needing additional listings or certifications, Eaton recommends contacting the factory to discuss options and lead times for specific regulatory approvals beyond RoHS.
By providing robust 48 Vdc protection with a switchable disconnect, CB185P-80 reduces downtime and maintenance complexity. The reliable interruption at 80 A and 3 kAIC minimizes wiring damage and component failures, leading to lower replacement costs and a faster mean time between failures (MTBF) in automotive or industrial control systems.
