FAQs
LESRK25 is designed for motor protection in 600 V systems, including fans, pumps, conveyors, and drives. With a 25 A rating and a 200 kAIC interrupt capacity, it handles startup surges and fault conditions effectively. Its RK1 class supports coordinated protection with upstream devices, making it a solid choice for standard industrial motor circuits.
The LESRK25 carries CSA Certified and UL Listed markings, signaling conformity to North American safety standards. This helps ensure regulatory compliance for industrial installations and simplifies supplier qualification for procurement teams working under stringent quality and safety requirements.
Non-indicating fuses do not provide a visual blown status in the indicator window. Maintenance teams should implement periodic verification with a test method or circuit monitoring to confirm fuse integrity. This approach reduces panel clutter and is common in densely packed electrical assemblies, provided a reliable testing routine is in place.
LESRK25 features a 5 inch length with 0.81 inch width and height, and weighs about 1.6 lb. It uses standard packaging and is designed for replacement in common Edison fuse blocks. Ensure the installation environment supports up to 600 V and verify panel space and mounting compatibilities in the target enclosure.
Using LESRK25 can lower total cost of ownership by reducing downtime through reliable motor protection, minimizing nuisance trips, and simplifying stocking with a standard 5 inch form factor. Its robust 200 kAIC interrupt rating and CSA UL certifications also help protect electrical assets and support long-term procurement stability.
