LPS-RK-100SP - 100Amp Fuse

LPS-RK-100SP - 100Amp Fuse

When you're matching a fuse for existing electrical equipment, the catalog number is only the beginning. The Eaton Bussmann series LPS-RK-100SP is a 100A Class RK1 time-delay, current-limiting fuse rated for 600VAC and 300VDC. When properly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPS-RK-100SP is built to last as part of a correctly designed and maintained electrical system.

Key Features and Benefits

• 100A Class RK1 configuration: The 100-amp rating and Class RK1 designation provide two essential checkpoints when matching the fuse to compatible equipment.
• Time-delay operation: Eaton specifies time-delay characteristics for the LPS-RK-100SP, an important consideration when confirming the required fuse type.
• Current-limiting fuse: The manufacturer identifies this model as current-limiting, helping distinguish it from fuses with different operating characteristics.
• Dual-element construction: Uses the dual-element design Eaton specifies for this catalog number.
• 600VAC / 300VDC ratings: Supports applications requiring the fuse's specified AC or DC voltage rating.
• Blade end × blade end connection: A key physical detail to confirm when evaluating form and fit.
• Non-indicating configuration: Eaton identifies this fuse as non-indicating.

Where It Works Best

The Eaton Bussmann LPS-RK-100SP 100A Class RK1 fuse is intended for compatible electrical equipment that requires its specific combination of 100A current rating, 600VAC / 300VDC voltage ratings, Class RK1 construction, time-delay operation, current-limiting characteristics, dual elements, and blade-end × blade-end connection. Its electrically isolated end cap is another catalog-specific feature worth checking when matching the required fuse.
