LPN-RK-110SP - 110 Amp Fuse

LPN-RK-110SP - 110 Amp Fuse

When you're matching a fuse to existing electrical equipment, the catalog number is only the beginning. The Eaton Bussmann series LPN-RK-110SP is a 110A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 250VDC. Eaton also lists high in-rush current motor protection as a special feature of this model. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPN-RK-110SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 110A Class RK1 configuration: Combines a 110-amp rating with the specified Class RK1 design, providing clear identification points when matching the fuse to compatible equipment.
• 250VAC and 250VDC ratings: Supports applications requiring the manufacturer's specified AC or DC voltage rating.
• Time-delay operation: Designed with time-delay characteristics for applications requiring this type of fuse response.
• Current-limiting fuse: Eaton identifies the LPN-RK-110SP as current-limiting, an important characteristic to confirm when selecting circuit protection.
• Dual-element construction: Uses two-element construction as specified by the manufacturer.
• Blade end × blade end connection: Provides a specific connection configuration that can be checked against the fuse holder and equipment requirements.
• Non-indicating configuration: Eaton identifies this model as non-indicating.

Where It Works Best

The Eaton Bussmann LPN-RK-110SP 110A Class RK1 fuse is intended for compatible electrical equipment that requires its specific combination of time-delay operation, current-limiting characteristics, dual-element construction, 250VAC / 250VDC ratings, and blade-end × blade-end connections. Its manufacturer-identified high in-rush current motor protection is especially relevant when evaluating the fuse for compatible motor circuits.
