LPN-RK-225SP - 225 Amp Fuse

LPN-RK-225SP - 225 Amp Fuse

Choosing a fuse by amperage alone can lead to the wrong match. The Eaton Bussmann series LPN-RK-225SP is a 225A 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, giving electrical professionals clear values to compare with circuit and equipment requirements. When you correctly select, install by qualified electrical personnel, and operate within its specified ratings, the LPN-RK-225SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 225A Class RK1 configuration: Combines a 225-amp rating with the Class RK1 designation, giving you two essential specifications to verify when matching the fuse to compatible equipment.
• 250VAC and 250VDC ratings: Rated for both AC and DC applications within the manufacturer's stated limits.
• Time-delay operation: Eaton identifies the LPN-RK-225SP as a time-delay fuse, an important operating characteristic when selecting protection for compatible circuits.
• Current-limiting design: Provides the manufacturer-specified current-limiting characteristic required for applications designed around this fuse type.
• Dual-element construction: Uses Eaton's specified dual-element configuration.
• Blade end × blade end connection: Makes the connection style easy to identify and verify against the intended equipment.
• Non-indicating: Eaton identifies this particular catalog number as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPN-RK-225SP 225A Class RK1 fuse is intended for compatible electrical equipment requiring its specific combination of 225A capacity, 250VAC / 250VDC ratings, time-delay operation, current-limiting characteristics, dual-element construction, and blade-end × blade-end connection. Eaton's stated high in-rush current motor protection is especially relevant when evaluating the LPN-RK-225SP for compatible motor applications.
