Eaton 8CLS-30 CLS Fuse - Motor Start Protection 50 kAIC

The 50 kAIC interrupt rating is central to reliability in harsh industrial environments. It quickly clears faults in motor circuits, reducing arc energy and downstream damage, which translates to lower maintenance costs and shorter downtime. The rating also supports safer operation during fault conditions, enabling more predictable system behavior. A 7.2 kV voltage rating positions the 8CLS-30 for mid-voltage protection roles, aligning with typical motor controllers and motor starters. This enables safer system operation and better coordination with upstream protection devices, reducing nuisance trips under high inrush. The single-barrel construction with a compact footprint simplifies installation and spare-part management, saving panel space and streamlining procurement within the Bussmann series. The 30 A continuous rating provides precise protection for standard motor loads while preserving starting torque, improving protection coordination with driver electronics and soft-start interfaces. Physical dimensions—17.9 in length, 3 in width, 3 in height, and 9 lb weight—plus catalog notes for mounting support predictable installation planning and easier budgeting. For retrofit projects and new builds, compatibility with existing Bussmann protection schemes reduces engineering overhead and simplifies procurement across the Eaton Bussmann family.
