Eaton CB285P-60 circuit breaker - marine rated
Part Number: CB285P-60
Quick Summary
Eaton CB285P-60 circuit breaker protects 48 Vdc DC power systems on vessels and rugged equipment. Vibration, water exposure, and salty environments routinely degrade standard breakers, causing costly downtime. The unit is RoHS compliant and designed for marine use with waterproof sealing, single-pole operation, and switchable functionality. This combination supports safer, lower-maintenance DC protection and simplifies panel mounting in control enclosures. For engineers and procurement teams, it enables scalable, reliable protection across DC circuits while easing compliance and installation workflows.
