FAQs
The LESRK70 is a Class RK1 non-indicating fuse designed for motor protection in standard Eaton protection schemes. It fits typical RK1 fuse holders and panel layouts, with electrically isolated end caps that simplify wiring and reduce troubleshooting time. Installation should follow Eaton's guidelines for Bussmann Edison fuses, ensuring correct amperage rating, voltage rating, and proper alignment within the fuse block.
LESRK70 provides a high interrupt rating of 200 kAIC, enabling rapid fault interruption while tolerating substantial inrush during motor start-up. This reduces nuisance trips and protects winding insulation during surge events, supporting higher line availability in pumps, conveyors, and compressors without compromising safety or protection integrity.
Yes, the LESRK70 is RoHS compliant and carries both CSA Certified and UL Listed certifications. These marks indicate adherence to environmental and safety standards, easing regulatory approvals and supplier qualification for industrial control panels and motor protection assemblies.
The LESRK70 measures 7.88 in in length with a width and height of 1.11 in each, and weighs approximately 2.2 lb. These dimensions matter for enclosure fit, panel density, and clearances in crowded control cabinets. Standard packaging and 1-unit quantity alignment support straightforward stocking and rapid replacement in maintenance operations.
Choosing LESRK70 offers strong fault protection with a 70 A rating and 200 kAIC interrupt rating, reducing motor damage and downtime. The UL Listed and CSA Certified marks simplify compliance, while RoHS compatibility supports longer asset life in regulated environments. The non-indicating design lowers potential points of failure in indicators and end-cap assemblies, reducing maintenance overhead and inventory complexity.
