Special features
Indicating, High in-rush current motor protection
High in-rush current protection is engineered to shield motors from surge faults during startup, reducing nuisance trips and protecting drive electronics. Business impact: increased equipment uptime and lower maintenance costs in conveyors, pumps, and fans; Application: 600 V motor circuits in industrial facilities benefit from dependable start-up reliability. The fuse’s 250 A rating with a 600 V rating and 200 kAIC interrupt capacity delivers robust short-circuit protection, limiting damage to cables and switchgear. Business impact: diminished repair costs and extended equipment life; Application: motor control centers and switchgear panels in harsh manufacturing environments. Certifications and compliance are ensured by UL Listed and CSA Certified markings, simplifying supplier qualification and regulatory alignment. Business impact: faster procurement, validated safety, and risk reduction; Application: regulated facilities requiring documented conformity. The non-indicating fuse indicator design reduces local signaling complexity in compact installations, while external monitoring options can be used where visibility is needed. Business impact: streamlined installation and reduced maintenance overhead; Application: remote MCCs and sealed control panels. The compact footprint and standard packaging support easy integration with Eaton Edison layouts and existing spare-part inventories. Business impact: faster project timelines and simplified stocking; Application: retrofits and new builds in space-constrained switchgear assemblies.

FAQs
The LESRK250I is designed for standard Eaton Edison fuse blocks and compatible MCC architectures. It supports a 250 A rating, 600 V operation, and fits within typical 11.63 inch body length with a 2.36 inch width and height profile. This alignment simplifies replacement, stock management, and integration with existing Bussmann/Eaton protection schemes.
An interrupt rating of 200 kAIC indicates the maximum fault current the fuse can interrupt safely without welding or sustaining damage. This provides robust protection for high-energy faults, reducing the risk of damage to motor windings, cables, and downstream protective devices in industrial power circuits.
Yes. The LESRK250I is specifically specified for high in-rush current motor protection, making it well suited for drives, pumps, fans, and conveyors operating at 600 V. Its 250 A rating supports large motors, while the 200 kAIC interrupt rating helps contain fault conditions without compromising downstream equipment.
The LESRK250I carries UL Listed and CSA Certified markings, underscoring safety and compliance with widely recognized electrical standards. These certifications facilitate procurement approvals, regulatory audits, and cross-site acceptance, especially in industries with stringent safety and quality requirements.
This model features a non-indicating fuse indicator, meaning no local trip status is shown on the device itself. For visibility, integrate external signaling or monitoring in the control system. This approach reduces panel clutter in compact installations while still enabling reliable fault detection through upstream protection and diagnostics.
