FAQs
LENRK150 is designed for high inrush motor protection with a 150 A rating and 200 kAIC interrupt capacity. It tolerates startup surges that commonly trip lesser fuses, preserving drive integrity and reducing unplanned downtime. This makes it well-suited for motor starters, conveyors, and HVAC drives where reliable startup is essential.
Yes. LENRK150 uses standard packaging (1 unit) and has a Class RK1 designation with a 250 Vac / 125 Vdc voltage rating, aligning with common panel design practices. Its non-indicating design and electrically isolated end caps simplify installation and reduce panel clutter, making it a straightforward drop-in for many Eaton Edison configurations.
LENRK150 carries UL Listed and CSA Certified markings, along with RoHS compliance. These certifications affirm electrical safety, product reliability, and environmental responsibility, easing regulatory approvals, supplier qualification, and supplier-diversity strategies for regulated industries such as food processing, plastics, and packaging where compliance matters.
Install LENRK150 with electrically isolated end caps as specified, in standard 1-pack packaging for easiest stocking. Ensure the 150 A rating and 200 kAIC interrupt capability align with your panel’s short-circuit current and motor protection strategy. The non-indicating design reduces visual clutter, while UL/CSA RoHS compliance supports safe, compliant commissioning.
Applications with high inrush current motors, such as pump drives, fans, conveyors, and HVAC equipment, benefit most. LENRK150 offers robust motor protection, fast interruption for faults, and straightforward replacement in standard control circuits, delivering reliability, reduced downtime, and simpler procurement for OEMs and service teams.
