Eaton 8ACLS-6R Fuse - 7.2 kV, 170 A, 50 kAIC
Part Number: 8ACLS-6R
Quick Summary
The 8ACLS-6R fuse from Eaton protects motor circuits, delivering fast, reliable overcurrent interruption for demanding industrial starts. Maintenance teams often grapple with nuisance trips and downtime; this device aims to minimize both by matching high interrupt ratings to motor inrush. Notable certifications in the spec include IEEE Std. C37.41 (not applicable) and a broad compliance stance; consult the factory for region-specific approvals. Beyond protection, the AmpGard mounting and Class R design streamline installation, improve serviceability, and support reliable motor-start protection for critical processes. Businesses benefit from predictable protection curves, reduced spares inventory, and faster changeouts when evaluating ACLS fuses for heavy-duty drive systems.

FAQs
The 8ACLS-6R uses AmpGard mounting, featuring a single-barrel design for compact protection in standard Eaton Bussmann assemblies. Installation involves aligning the fuse with the AmpGard holder, securing the barrel, and consulting factory notes for mounting compatibility. This approach minimizes misalignment and speeds field service during motor-start protection upgrades. Engineers appreciate the simplified wiring path and reduced likelihood of installation errors.
The fuse is rated for 7.2 kV, 170 A, with an interrupt rating of 50 kAIC. This combination supports reliable fault interruption during motor starts and under short-circuit conditions, reducing damage to drives and downstream equipment. These ratings enable selective coordination with upstream protection and improve overall drive system resilience.
Yes. The 8ACLS-6R is designed for high-energy circuits associated with motor starts, providing ACLS protection with a Class R designation. Its AmpGard mounting and substantial interrupt capability help manage inrush while maintaining protection levels. For extreme duty cycles, verify regional standards and test coordination with upstream fuses and starters in your application.
The datasheet lists IEEE Std. C37.41 as Not Applicable, and other compliance notes vary by region. This means regional approvals may differ and it’s important to confirm requirements with Eaton. Consult the manufacturer for current certification status, approval pathways, and any additional documentation needed for your installation in your facility environment.
The 8ACLS-6R offers robust protection with a single-barrel design that simplifies replacement, reduces spares, and lowers downtime during maintenance. Its AmpGard mounting facilitates quick field changes, while the Class R protection supports coordinated protection. These features translate to higher equipment uptime, predictable maintenance planning, and lower total cost of ownership.
