FAQs
The LESRK35 is designed for 35 A motor circuits up to 600 V and integrates with Eaton Edison fuse blocks. It adheres to Class RK1 protection standards and carries CSA Certified and UL Listed certifications, ensuring compatibility with common North American electrical panels and typical motor control centers found in manufacturing and processing facilities.
A 200 kAIC interrupt rating indicates the fuse can safely interrupt high fault currents up to 200 kiloamps at its rated voltage. This provides robust protection for large motors and feeders, preventing damage to conductors and equipment during short-circuit events while maintaining system reliability.
Yes. The LESRK35 is engineered for high inrush motor protection, minimizing nuisance trips during startup. This is particularly beneficial in conveyor systems and other equipment with frequent starting events, where protecting motor windings and drives while maximizing uptime is critical.
LESRK35 carries UL Listed and CSA Certified markings, which verify compliance with recognized safety and performance standards. These certifications help meet regulatory requirements, support product acceptance in global markets, and reduce project risk during procurement and installation.
LESRK35 is a non-indicating fuse, so visual status is not available; perform periodic electrical checks or use testing instruments to confirm operability. Plan for stock replacement, follow standard Eaton Edison guidelines, and verify compatibility with existing fuse blocks to ensure consistent protection and minimize downtime during maintenance.
