LPN-RK-6SP - 6 Amp Fuse

LPN-RK-6SP - 6 Amp Fuse

Getting the right fuse means checking more than the amperage printed on the label. The Eaton Bussmann series LPN-RK-6SP is a 6A 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, this fuse is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 6A Class RK1 configuration: Combines the specified 6-amp rating with the Class RK1 configuration required by compatible equipment.
• Time-delay operation: Eaton identifies the LPN-RK-6SP as a time-delay fuse, an important characteristic to confirm when matching an existing application.
• Current-limiting design: Current-limiting operation is part of the manufacturer's stated fuse configuration.
• Dual-element construction: Uses the dual-element construction specified by Eaton for this catalog number.
• 250VAC and 125VDC ratings: Separate AC and DC ratings provide clear reference points when checking application requirements.
• 8-second response at 500%: Eaton lists a response time of 8 seconds at 500%, giving another specification to confirm during fuse selection.
• Ferrule End × ferrule end connection: Provides a specific physical connection detail for form-and-fit verification.
• Non-indicating configuration: Eaton identifies this model as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPN-RK-6SP 6A Class RK1 fuse is intended for compatible electrical equipment requiring a 6A rating, 250VAC / 125VDC voltage ratings, Class RK1 configuration, time-delay operation, current-limiting characteristics, dual-element construction, and ferrule-end × ferrule-end connection. Its electrically isolated end cap is another catalog-specific feature to consider when checking the required fuse configuration.
