LPN-RK-70SP - 70 Amp Fuse

LPN-RK-70SP - 70 Amp Fuse

When you're matching a fuse to existing electrical equipment, the catalog number is only the beginning—the electrical ratings, fuse class, connection style, and physical dimensions must all line up. The Eaton Bussmann series LPN-RK-70SP is a 70A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 250VDC. When properly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPN-RK-70SP is built to last as part of a correctly designed and maintained electrical system.

Key Features and Benefits

• 70A Class RK1 configuration: Provides the manufacturer-specified 70-amp rating in a Class RK1 fuse for compatible equipment.
• Time-delay operation: Eaton identifies the LPN-RK-70SP as a time-delay fuse, an important operating characteristic to match when selecting a fuse for an existing application.
• Current-limiting characteristics: Current-limiting operation is part of the manufacturer's specified fuse design.
• Dual-element construction: Uses the dual-element configuration Eaton specifies for this catalog number.
• 250VAC / 250VDC ratings: Rated for both AC and DC applications within the manufacturer's stated electrical limits.
• Blade end × blade end connection: Gives you another important physical specification to verify before installation.
• Non-indicating configuration: Eaton identifies this particular fuse as non-indicating.

Where It Works Best

The Eaton Bussmann LPN-RK-70SP 70A Class RK1 fuse is intended for compatible electrical equipment requiring its specific combination of a 70A rating, 250VAC / 250VDC voltage ratings, time-delay operation, current-limiting characteristics, dual-element construction, and blade end × blade end connection. The manufacturer-listed electrically isolated end cap is another catalog-specific detail to check when identifying the correct fuse.
