LPN-RK-30SP - 30 Amp Fuse

LPN-RK-30SP - 30 Amp Fuse

Choosing the right fuse takes more than matching the amp rating. The Eaton Bussmann series LPN-RK-30SP is a 30A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 125VDC. Eaton specifies an interrupting rating of 300 kAIC at 250VAC and 100 kAIC at 125VDC, dual-element construction, and a manufacturer-stated response time of 8 seconds at 500%. When correctly selected, installed by your qualified electrical personnel, and operated within its specified ratings, the LPN-RK-30SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 30A Class RK1 configuration: Combines Eaton's specified 30-amp rating with a Class RK1 fuse configuration for applications requiring these characteristics.
• 250VAC / 125VDC ratings: Provides clear AC and DC voltage ratings to check against circuit requirements.
• Time-delay operation: Eaton identifies the LPN-RK-30SP as a time-delay fuse, an important operating characteristic when selecting a fuse for compatible equipment.
• Current-limiting design: Manufacturer specifications classify this model as current-limiting.
• Dual-element construction: Uses the dual-element configuration specified by Eaton.
• 8-second response at 500%: Eaton specifies a response time of 8 seconds at 500%.
• Ferrule End × ferrule end connection: Gives you a defined physical connection style to verify against the fuse holder and equipment.

Where It Works Best

The Eaton Bussmann LPN-RK-30SP 30A Class RK1 fuse is intended for compatible electrical equipment requiring its particular combination of a 30A rating, 250VAC / 125VDC voltage 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 the LPN-RK-30SP for compatible motor applications.
