LPN-RK-1SP - 1 Amp Fuse

LPN-RK-1SP - 1 Amp Fuse

When you match a fuse to existing electrical equipment, the small details matter as much as the amp rating. The Eaton Bussmann series LPN-RK-1SP is a 1A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 125VDC. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPN-RK-1SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 1A Class RK1 configuration: Combines a 1-amp rating with the Class RK1 designation for applications requiring these specific characteristics.
• 250VAC and 125VDC ratings: Clearly defined AC and DC ratings help with accurate equipment matching.
• Time-delay operation: Eaton identifies the LPN-RK-1SP as a time-delay fuse, an important characteristic when selecting protection for compatible circuits.
• Current-limiting fuse: Provides the manufacturer-specified current-limiting characteristics of this LPN-RK model.
• Dual-element construction: Uses Eaton's specified dual-element configuration.
• Ferrule End × ferrule end connection: Provides a physical connection characteristic that can be checked against the existing fuse and equipment.
• Non-indicating: Eaton identifies the LPN-RK-1SP as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPN-RK-1SP 1A Class RK1 fuse is intended for compatible electrical equipment that requires its specific combination of 1A capacity, 250VAC / 125VDC ratings, Class RK1 construction, time-delay operation, current-limiting characteristics, dual elements, and ferrule-end connections. Eaton's stated high in-rush current motor protection is another specification to consider when evaluating the fuse for compatible motor applications.
