Eaton Specification Sheet - 8CLS-5R
Feature → Business Impact → Application: The 8CLS-5R uses a single-barrel, Class R design that minimizes panel footprint while delivering high interrupt capacity; this translates to more compact motor control centers and easier wiring in space-constrained installations. Application: motor-start protection for pumps, conveyors, and fans in automated lines. Feature → Business Impact → Application: 150 A rating with 50 kAIC interrupt capability ensures rapid fault clearance, reducing arc energy and downtime costs during faults in drive systems. Application: drive protection and motor starter circuits in manufacturing lines. Feature → Business Impact → Application: 7.2 kV voltage rating supports higher system voltages, enabling safer integration in mid- to high-voltage panel boards. Application: electrical protection in mezzanines and switchgear with strict clearance needs. Feature → Business Impact → Application: 1-barrel simplicity and 5R designation streamline installation and replacement, lowering maintenance time during outages. Application: retrofits and new builds in control panels. The solution aligns with long-tail use cases such as “CLS fuse 150A motor-start protection,” “industrial fuse for panel protection,” and “Bussmann CLS series for conveyors,” helping engineers meet reliability, compliance, and lifecycle cost goals.

FAQs
The 8CLS-5R is a single-barrel CLS fuse rated for 150 A with 50 kAIC interrupt capability and a 7.2 kV voltage rating. It is suited for motor-start protection, drives, and panel protection in industrial control circuits where space is at a premium and high fault clearance is required.
Install the fuse in an appropriate holder or fuse block designed for CLS fuses. Ensure correct orientation, tighten terminal connections to recommended torque, and verify clearance for 7.2 kV circuits. After installation, test continuity and verify amperage rating matches the motor-start or drive load to prevent nuisance trips.
Ideal for motor-start protection in conveyors, pumps, fans, and other motor-driven equipment within automated lines. Suitable for panelboard protection and switchgear where a compact, high-interrupt fuse is needed to protect against short circuits without occupying excess space.
The data provided lists no explicit certifications. For compliance specifics such as CE, UL, or IP ratings, refer to Eaton’s specification sheets or contact the manufacturer to confirm current approvals and installation guidelines for your region and application.
With a high interrupt rating and a compact form factor, the 8CLS-5R reduces downtime during fault events and minimizes spare-part complexity. Its robust motor-start protection helps prevent nuisance trips in variable-speed drives and assemblies, contributing to lower maintenance costs and improved overall equipment effectiveness (OEE).
