Eaton Specification Sheet - CB185-60
60 A amperage rating, 48 Vdc electrical rating, and 3 kAIC interrupt rating provide robust protection for automotive circuits; this reduces fault-induced damage and lowers downstream repair costs. The waterproof housing protects electronics from splash, moisture, and wash-downs, cutting corrosion risk and maintenance frequency in exposure-prone environments. Switchable operation allows quick manual disconnection during diagnostics, minimizing servicing risk and enabling safer maintenance workflows in busy automotive setups. Flush mounting saves panel space, enables compact control-panel layouts, and simplifies integration with standard Eaton Bussmann assemblies for faster design iterations. RoHS compliant manufacturing supports regulatory compliance across global production, reducing environmental risk and easing international sourcing for OEMs and tier suppliers.

FAQs
Install CB185-60 in a flush-mounted position on a suitable panel space, aligning with the mounting footprint and securing with the recommended hardware. Connect input and output conductors to the rated terminals, observing proper torque values from Eaton’s datasheet. Ensure the enclosure remains sealed against moisture and verify the switch is in the OFF position before energizing. Use appropriate wire gauges for 60 A loads.
The 60 A rating defines the continuous operating current the device can carry. The 3 kAIC rating indicates the maximum fault current it can interrupt safely. The 48 Vdc rating specifies the maximum DC operating voltage. Together, these specs indicate suitability for automotive power distribution, battery circuits, and other 48 V systems where reliable overcurrent protection is essential.
Yes. The CB185-60 features a waterproof housing designed to withstand exposure to moisture, wash-downs, and vibration typical in automotive and marine environments. Its flush-mount design minimizes ingress paths, and the Type III switching provides dependable operation after exposure to harsh conditions. This makes it well-suited for off-road, agricultural, and industrial vehicles.
CB185-60 is RoHS compliant, aligning with global environmental and regulatory requirements. The 3 kAIC interrupt rating and rugged construction meet industry expectations for high-reliability automotive protection devices. For additional certifications or approvals, users should consult Eaton's specification sheet or contact the manufacturer to confirm region-specific requirements.
The switchable design and rugged waterproof construction reduce maintenance downtime by enabling quick fault isolation and reset. High interrupt reliability minimizes collateral damage to wiring and components, lowering repair costs and warranty exposure. Compatibility with standard Bussmann lines simplifies stocking, while regulatory compliance and longer service life contribute to total cost of ownership reductions over vehicle and equipment lifecycles.
