FAQs
LESRK125I fuses are 9.63 in long, 1.11 in wide, and weigh about 1.1 lb, with electrically isolated end caps for safer wiring. They are designed for standard panel mounting and come in a 1‑pack quantity. Ensure enclosure clearances accommodate the depth and maintain proper clearance from live conductors. Use appropriate rated holders and follow manufacturer wiring diagrams for correct ampacity and fault protection alignment.
The LESRK125I is rated for 125 A, with a 200 kAIC interrupt rating and a voltage rating of 600 V. It is UL Listed and CSA Certified, ensuring compliance with common electrical protection standards. These ratings support reliable motor protection in industrial drives and motor control centers while enabling safe, code-compliant installation.
Yes. The LESRK125I is specifically designed for high-inrush current motor protection, delivering rapid interrupt capability (200 kAIC) to safely handle startup surges. Its 125 A rating and 600 V compatibility make it suitable for demanding industrial motors and drive systems where startup transients are a concern, helping reduce nuisance trips and equipment wear.
LESRK125I carries UL Listed and CSA Certified marks, signaling compliance with recognized safety and performance standards. These certifications simplify procurement by meeting regulatory requirements for industrial protection devices and help ensure the fuse delivers consistent, reliable protection in motor circuits and control panels.
Because LESRK125I is a non-indicating fuse, visual status indication isn’t available; plan for periodic electrical testing and verification of protection integrity during maintenance cycles. With a 9.63 inch length and 1.11 inch width, ensure replacement fuses match the exact catalog number LESRK125I to preserve fiber insulation and end-cap isolation, maintaining UL and CSA compliance.
