LPN-RK-250SP - 250 Amp Fuse

LPN-RK-250SP - 250 Amp Fuse

When you're matching a replacement fuse, the 250A rating is only the starting point. The Eaton Bussmann series LPN-RK-250SP is a 250A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 250VDC. Eaton specifies interrupting ratings of 300 kAIC at 250VAC and 100 kAIC at 250VDC, along with a dual-element design and blade-end × blade-end connection. Correctly selected, professionally installed, and operated within its specified ratings, the LPN-RK-250SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 250A Class RK1 fuse: Provides the specific 250-amp and Class RK1 configuration required by compatible electrical equipment.
• Time-delay operation: Eaton identifies this model as a time-delay fuse, an important operating characteristic to match when replacing an existing fuse.
• Current-limiting: The LPN-RK-250SP is manufacturer-specified as a current-limiting fuse.
• Dual-element construction: Uses the dual-element design specified for this catalog number.
• 250VAC / 250VDC ratings: Supports compatible AC and DC applications within the fuse's specified electrical ratings.
• Blade end × blade end connection: Gives technicians a clear connection characteristic to check when confirming form and fit.

Where It Works Best

The Eaton Bussmann LPN-RK-250SP 250A Class RK1 fuse is intended for compatible electrical equipment requiring its specific combination of a 250A amperage rating, 250VAC / 250VDC voltage ratings, Class RK1 configuration, time-delay operation, current-limiting characteristics, dual-element construction, and blade-end × blade-end connection. Eaton's listing of high in-rush current motor protection is another characteristic to consider when evaluating the fuse for compatible motor protection applications.
