Feature ā Business Impact ā Application: The KRP-C-750SP is a time-delay, current-limiting Class L fuse that tolerates motor inrush while protecting downstream equipment, reducing nuisance trips and extending component life in drive and motor circuits. This translates to fewer unplanned outages and lower maintenance costs in manufacturing lines. Application: motor starters, conveyors, and heavy machinery in automotive, packaging, and process industries. Feature ā Business Impact ā Application: With an interrupt rating of 300 kAIC at 600 Vac, the fuse clears faults rapidly, minimizing arc energy and damage to feeders and switchgear, which lowers repair expenses and downtime in critical power feeds. Application: main distribution panels and MCCs in heavy industry. Feature ā Business Impact ā Application: The compact footprint (8.63 in length, 2.53 in width, 2.53 in height) and standard bolted blade ends enable straightforward panel mounting and fast installation, reducing project lead times and space constraints in control cabinets. Application: compact control enclosures and retrofit projects. Feature ā Business Impact ā Application: Bolted blade end x bolted blade end construction provides robust vibration resistance and reliable connection integrity in demanding environments, improving service life and reducing recalibration or reseating requirements. Application: mine, steel, and high-vibration facilities. Feature ā Business Impact ā Application: CE marking and RoHS compliance ensure global regulatory alignment and safer material usage, supporting international deployments and supplier audits. Application: OEM equipment, global food and beverage lines, and energy utilities. Feature ā Business Impact ā Application: A 4-second response time at 500% overcurrent delivers predictable protection curves, enabling precise coordination with upstream breakers and downstream devices. Application: protective relays, power quality programs, and systems requiring defined fault clearing.

FAQs
The KRP-C-750SP uses bolted blade ends and measures 8.63 in length, with 2.53 in width and 2.53 in height. Install by aligning with compatible bus bars and mounting hardware in a properly rated enclosure. Follow Eatonās datasheet for torque specs, secure alignment, and clear labeling to ensure safe, vibration-resistant operation in high-current circuits.
The fuse is rated for 750 A, with a voltage rating of 600 Vac and 300 Vdc. Its interrupt rating is 300 kAIC at 600 Vac and 100 kA at 300 Vdc. It provides a 4-second response time at 500% overcurrent, combining fast fault clearing with tolerance for motor inrush in industrial drives.
Yes. The time-delay, current-limiting Class L design is ideal for protecting motors and feed circuits while accommodating inrush currents. Its Class L characteristics, along with the 750 A rating and bolted blade connections, suit motor control centers, MCC feeders, and space-constrained panel layouts in manufacturing and process facilities.
The KRP-C-750SP is CE-marked and RoHS compliant, aligning with European regulatory requirements and restricted hazardous substances guidelines. This supports global deployments, supplier audits, and safer material usage in regulated industries such as automation, energy, and food & beverage.
Expected benefits include reduced downtime from fewer nuisance trips, longer service life of protected equipment due to controlled fault energy, and easier replacement with a compact footprint. The robust bolted-end design minimizes connection issues in vibration-prone environments, contributing to lower maintenance costs and improved overall equipment effectiveness (OEE).
