LPN-RK-175SP - 175 Amp Fuse

LPN-RK-175SP - 175 Amp Fuse

Choosing the right fuse means checking more than amperage. The Eaton Bussmann series LPN-RK-175SP is a 175A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 250VDC, with Eaton-specified interrupting ratings of 300 kAIC at 250VAC and 100 kAIC at 250VDC. If indication capability is important for your application, verify that characteristic before installation. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPN-RK-175SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 175A Class RK1 fuse: Provides the specific amperage and fuse-class combination needed when matching compatible equipment.
• 250VAC and 250VDC ratings: Supports applications requiring the manufacturer's stated AC or DC voltage rating.
• Time-delay operation: An important characteristic to consider when the application calls for a Class RK1 time-delay fuse.
• Current-limiting design: Eaton identifies the LPN-RK-175SP as a current-limiting fuse.
• Dual-element construction: Uses the manufacturer's specified dual-element configuration.
• Blade end × blade end connection: Gives installers another physical checkpoint when confirming compatibility with existing equipment.

Where It Works Best

The Eaton Bussmann LPN-RK-175SP 175A Class RK1 fuse is intended for compatible electrical equipment that requires its specific combination of 175A current rating, 250VAC / 250VDC voltage ratings, time-delay operation, current-limiting characteristics, dual-element construction, and blade-end connections. Eaton's stated high in-rush current motor protection is another characteristic to consider when evaluating the fuse for compatible motor circuits.
