Yes. The LESRK25I is a compact 5 in long fuse with a 0.81 in by 0.81 in footprint, designed to fit within standard motor control centers (MCCs) and enclosure spaces without significant rearrangement. Its standard packaging supports straightforward replacement, and the non-indicating design minimizes nuisance alarms in busy panels, improving maintenance efficiency.
The LESRK25I is rated for 25 A at 600 V with a 200 kAIC interrupt rating. This combination provides reliable protection against short circuits while tolerating the inrush currents typical of large motors at start-up, helping to protect both motor windings and switchgear.
Ideal for industrial drives, conveyors, and pumps where motors experience high inrush during start-up. It supports 600 V systems and 25 A circuits, making it suitable for motor control centers and electrical protection schemes that require robust interruption capabilities and dependable motor protection in harsh industrial environments.
The LESRK25I carries UL Listed and CSA Certified markings, ensuring compliance with widely recognized safety and performance standards. These certifications facilitate regulatory acceptance and help streamline procurement for facilities that require formal certification as part of their electrical protection strategy.
By delivering high inrush protection and a robust 200 kAIC interrupt rating, the LESRK25I reduces fault-induced downtime and protects motor assets, lowering maintenance costs over time. Its compact, standard form factor simplifies stocking and replacements, contributing to lower total cost of ownership in motor protection programs.
