FAQs
The 8ACLS-2R uses AmpGard mounting and is a single-barrel ACLS fuse with a 2R designation, designed for straightforward installation in panels. For non-standard enclosures, consult the factory for compatible mountings and ensure the panel cutouts, bus bar connections, and wire terminations meet Eaton guidelines. Typical installation steps include verifying voltage and current ratings, securing the fuse in the AmpGard holder, and routing wiring to minimize heat buildup and allow for easy replacement.
The 8ACLS-2R provides a 7.2 kV voltage rating, 70 A amperage rating, and a 50 kAIC interrupt rating. These specifications enable effective protection for high-energy motor-start circuits, allowing rapid fault interruption to minimize motor damage and downtime while supporting reliable operation under startup and fault conditions in industrial drives.
Yes. The combination of a 7.2 kV rating, 70 A current rating, 50 kAIC interrupt capability, and AmpGard mounting makes the 8ACLS-2R well suited for motor-start protection in conveyor systems and other high-energy drive environments. Its single-barrel design helps maintain a compact panel footprint while delivering robust protection for start-up surges.
Catalog data lists IEEE Std. C37.41 as a reference with Not Applicable, and there is no explicit CE or SIL certification shown. In practice, verify site-specific approvals with the manufacturer and align with your facility’s regulatory requirements. Always confirm current certifications and approvals for your target market and application before deployment.
The 8ACLS-2R offers a robust, single-barrel design with a 2R designation, reducing spare-part diversity and simplifying inventory. Its high interrupt rating and durable AmpGard mounting contribute to lower failure rates and faster replacement, which translates to less unplanned downtime and improved total cost of ownership in facilities with frequent motor-start protection needs.
