LPN-RK-10SP - 10 Amp Fuse

LPN-RK-10SP - 10 Amp Fuse

Choosing the right fuse means checking more than the amperage stamped on the label. The Eaton Bussmann series LPN-RK-10SP is a 10A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 125VDC. The manufacturer also highlights high in-rush current motor protection as a special feature, making it worth considering when matching the fuse to compatible motor circuits and equipment. When you select it correctly, install it with qualified electrical personnel, and operate it within its specified ratings, the LPN-RK-10SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 10A Class RK1 fuse: Combines a 10-amp rating with the manufacturer's specified Class RK1 configuration, giving you two important selection points to verify against equipment documentation.
• 250VAC / 125VDC ratings: Suitable for compatible AC or DC equipment requiring these specified voltage ratings.
• Time-delay operation: Eaton specifies a response time of 8 seconds at 500% of rated current.
• Current-limiting design: Eaton identifies the LPN-RK-10SP as a current-limiting fuse, an important characteristic when matching circuit protection requirements.
• Dual-element construction: Uses the manufacturer's specified dual-element configuration.
• Ferrule End × ferrule end connection: Gives installers a defined connection style to verify against the existing fuse holder or equipment.
• Non-indicating: Eaton identifies the LPN-RK-10SP as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPN-RK-10SP 10A Class RK1 fuse is intended for compatible electrical equipment requiring a 10A rating, 250VAC / 125VDC voltage ratings, time-delay operation, current-limiting characteristics, dual-element construction, and a ferrule-end × ferrule-end connection. Eaton's stated high in-rush current motor protection is also relevant when evaluating the fuse for compatible motor applications.
