Eaton Specification Sheet - BK/CB185-60
Electrical rating and protection level are engineered to deliver precise overcurrent protection for 60 A at 48 Vdc with a 3 kAIC interrupt capability, reducing harness damage and costly downtime in automotive power distribution. This translates to higher equipment availability in fleets and service trucks, where quick restoration of power is critical. The rugged waterproof design supports reliable operation in exposed environments, minimizing corrosion and failure risks in on-vehicle and outdoor installations. Type III, switchable capability enables straightforward resets and field servicing, reducing maintenance time and enabling faster diagnostics during routine checks or after fault events. Flush mounting with standard packaging and SEMS-nut compatibility accelerates installation on crowded panels, lowering labor costs and simplifying retrofits in retrofit projects. RoHS compliance ensures regulatory alignment across global supply chains, enabling smoother procurement in multi-region programs while keeping hazardous substances out of the rebuild cycle. The combination of these features supports Bussmann series compatibility, providing a cohesive protection strategy for automotive circuits and industrial power management.
