FAQs
LESRK80 is designed for standard Edison fuse mounting within motor control centers. It matches the RK1 form factor and uses electrically isolated end caps for safer maintenance. With a length of 7.88 in and a width of 1.11 in, it fits typical RK1 panels and allows straightforward retrofits. Verify busbar spacing and enclosure clearance to ensure proper installation.
The LESRK80 provides an 80 A amperage rating, a 600 V voltage rating, and a 200 kAIC interrupt rating. This means it can safely interrupt high fault currents in motors and drives at standard industrial voltages, while protecting circuitry from inrush surges and minimizing damage to downstream components during faults.
Yes. LESRK80 is a non-indicating fuse designed for motor protection in high inrush environments. Its RK1 Class designation supports motor protection needs in drive panels, and its non-indicating nature reduces visual clutter in control rooms. For critical signaling zones, consider indicating alternatives, but for general protection, this model is well-suited.
LESRK80 carries UL Listed and CSA Certified certifications and RoHS compliance, meeting common electrical safety and environmental requirements for global installations. These certifications provide confidence in panel approvals, procurement, and regulatory adherence across markets.
By delivering reliable high-inrush protection with a robust 200 kAIC interrupt rating, LESRK80 minimizes nuisance trips and motor damage, reducing downtime and maintenance costs. The RoHS, UL, and CSA certifications simplify compliance, while the standard RK1 footprint and isolated end caps speed up field replacements and retrofits, delivering a favorable total cost of ownership for motor-driven systems.
