LPN-RK-15SP - 15 Amp Fuse

LPN-RK-15SP - 15 Amp Fuse

Finding the right fuse isn't just about matching the amp rating. The Eaton Bussmann series LPN-RK-15SP is a 15A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 125VDC. Eaton specifies interrupting ratings of 300 kAIC VAC and 100 kAIC VDC. At the same time, its dual-element construction and ferrule-to-ferrule connection provide additional electrical and physical characteristics to confirm when verifying compatibility. When you select it correctly, install it with qualified electrical personnel, and operate it within its specified ratings, the LPN-RK-15SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 15A Class RK1 configuration: Combines a 15-amp rating with the Class RK1 designation for compatible electrical equipment.
• 250VAC / 125VDC voltage ratings: Gives installers clear AC and DC ratings to check against circuit requirements.
• Time-delay characteristics: Eaton specifies a response time of 8 seconds at 500%, an important operating characteristic when evaluating the fuse for a particular application.
• Current-limiting design: Eaton identifies the LPN-RK-15SP as a current-limiting fuse.
• Dual-element construction: Uses two elements as specified by the manufacturer.
• Ferrule-to-ferrule connection: Provides another physical characteristic to verify when matching the fuse to existing equipment.
• Non-indicating: Eaton identifies the LPN-RK-15SP as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPN-RK-15SP 15A Class RK1 fuse is intended for compatible electrical equipment requiring its combination of 15A capacity, 250VAC / 125VDC ratings, time-delay operation, current-limiting characteristics, dual-element construction, and ferrule-end × ferrule-end connection. Eaton's stated high in-rush current motor protection is especially relevant when evaluating this fuse for compatible motor applications.
