LPN-RK-80SP - 80 Amp Fuse

LPN-RK-80SP - 80 Amp Fuse

Getting the fuse right means checking more than the amp rating printed on the label. The Eaton Bussmann series LPN-RK-80SP is an 80A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 250VDC. Eaton specifies interrupting ratings of 300 kAIC at 250VAC and 100 kAIC at 250VDC, with a dual-element design and a blade-end × blade-end connection. 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

• 80A Class RK1 fuse: Provides an 80-amp rating in the Class RK1 configuration specified by Eaton.
• Time-delay operation: Designed with the manufacturer-specified time-delay characteristic, an important detail when matching a fuse to compatible equipment.
• Current-limiting: Eaton identifies the LPN-RK-80SP as a current-limiting fuse.
• Dual-element construction: Uses the dual-element configuration specified for this catalog number.
• 250VAC and 250VDC ratings: Clearly defined AC and DC voltage ratings make it easier to compare the fuse against equipment requirements.
• Blade-end × blade-end connection: A key physical characteristic to verify when checking form and fit.
• Non-indicating: Eaton identifies this specific fuse as non-indicating.

Where It Works Best

The Eaton Bussmann LPN-RK-80SP 80A Class RK1 fuse is intended for compatible electrical equipment requiring an 80A rating, 250VAC / 250VDC voltage ratings, time-delay operation, current-limiting characteristics, dual-element construction, and a blade-end × blade-end connection. Its electrically isolated end cap is another manufacturer-listed characteristic worth checking when confirming the exact fuse needed for an application.
