Eaton LESRK150I Edison fuse - 200 kAIC motor protection
Part Number: LESRK150I
Quick Summary
The Eaton Edison LESRK fuse protects motor circuits with time-delay inrush handling for high-demand applications. One common pain point is nuisance tripping during motor start-ups when inrush currents spike. Note that CE, SIL, or IP certifications aren’t listed here; confirm with Eaton while relying on its 150 A, 600 V, 200 kAIC performance. This solution supports reliable motor protection and quick status indication, helping maintenance teams reduce downtime and improve control panel reliability.

FAQs
LESRK150I is designed for Eaton Edison fuse blocks and assemblies that accommodate Bussmann-style, dual-element indicating fuses. In practice, confirm mounting fit, alignment with the 9.63 in length and 1.61 in width, and ensure the panel provides 600 V-rated protection and proper clearance for safe operation.
Key specs include 150 A amperage rating, 600 V voltage rating, and 200 kAIC interrupt rating. The device features dual elements and an indicating status function, making it suitable for motor protection where inrush is common.
Yes. The time-delay design accommodates brief inrush currents typical of motors, reducing nuisance trips while still delivering rapid fault interruption up to 200 kAIC. This makes it well-suited for fans, pumps, conveyors, and drive motors.
The provided data lists Compliances and Warranty as Not Applicable, and does not specify CE, SIL, or IP certifications. For region-specific regulatory compliance, verify with Eaton to confirm any applicable certifications and compatibility with local electrical standards.
The indicating feature simplifies status checks, reducing maintenance time and downtime. With a high interrupt rating and durable construction, it offers reliable protection for motor circuits, contributing to longer equipment life and improved protection coordination in industrial facilities.
