LPN-RK-90SP - 90 Amp Fuse

LPN-RK-90SP - 90 Amp Fuse

Getting the right fuse means checking more than the amp rating printed on the label. The Eaton Bussmann series LPN-RK-90SP is a 90A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 250VDC. Eaton specifies an interrupting rating of 300 kAIC at 250VAC and 100 kAIC at 250VDC, giving maintenance and electrical professionals clear values to compare against your equipment requirements. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPN-RK-90SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 90A Class RK1 configuration: Provides the specific 90-amp, Class RK1 configuration required for compatible electrical equipment.
• Time-delay operation: Eaton identifies the LPN-RK-90SP as a time-delay fuse, an important operating characteristic when matching a fuse to circuit requirements.
• Current-limiting design: The manufacturer specifies this model as current-limiting.
• Dual-element construction: Uses the dual-element configuration Eaton specifies for this catalog number.
• 250VAC and 250VDC ratings: The defined AC and DC voltage ratings make it easier to verify the fuse against equipment and circuit specifications.
• Blade-end × blade-end connection: A key physical characteristic to verify when matching the fuse to an existing installation.
• Non-indicating configuration: Eaton identifies the LPN-RK-90SP as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPN-RK-90SP 90A Class RK1 fuse is intended for compatible electrical equipment that requires its specific combination of a 90A rating, 250VAC / 250VDC voltage ratings, Class RK1 construction, time-delay operation, current-limiting characteristics, dual elements, and a blade-end × blade-end connection. Its electrically isolated end cap is another catalog-specific detail to include when confirming the required fuse configuration.
