FAQs
LENRK50I is a 50 A, 250 V non-indicating fuse with a 200 kAIC interrupt rating designed for standard packaging (10 per box) and a 3 inch body length. It fits common Eaton Bussmann-style fuse blocks and motor control centers, enabling straightforward replacement and upgrade without reconfiguring wiring or panel layouts.
Best suited for industrial motor protection in drives, conveyors, pumps, and HVAC systems where high inrush is common. The 50 A rating, 250 V operation, and 200 kAIC interrupt capability make it ideal for protecting proximal motor starters and control panels from startup surges while preserving circuit integrity.
LENRK50I carries UL Listed and CSA Certified marks, validating safety and performance to widely adopted industrial standards. These certifications help with compliance audits, customer qualification, and smoother procurement in regulated facilities.
The 200 kAIC interrupt rating ensures rapid, high-energy fault clearance in motor circuits, reducing arc flash risk and downstream damage to cables, controllers, and drives. This is crucial for safeguarding equipment during short-circuit events and startup transients in heavy-duty applications.
LENRK50I is a non-indicating fuse with a no-warranty note in the spec. For maintenance, replace after fault events or according to preventive maintenance schedules, maintain stock of LENRK50I (10 per packaging) for timely replacements, and verify panel wiring and protective coordination to sustain reliability.
