LPN-RK-2SP - 2 Amp Fuse

LPN-RK-2SP - 2 Amp Fuse

Getting the right fuse means looking beyond amperage alone. The Eaton Bussmann series LPN-RK-2SP is a 2A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 125VDC. When correctly selected, installed by your qualified electrical personnel, and operated within its specified ratings, the LPN-RK-2SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 2A Class RK1 configuration: Provides the specific amperage and fuse-class combination needed when matching the LPN-RK-2SP to compatible equipment.
• 250VAC / 125VDC ratings: Eaton specifies this fuse for applications within these respective AC and DC voltage limits.
• Time-delay operation: Designed with the manufacturer's stated time-delay characteristic, an important consideration when the circuit requires this type of fuse behavior.
• Current-limiting fuse: Eaton identifies the LPN-RK-2SP as current-limiting.
• Dual-element construction: Eaton specifies a dual-element construction.
• High in-rush current motor protection: Eaton lists this as a special feature and worth considering when evaluating the fuse for compatible motor applications.
• Ferrule-to-ferrule connection: Gives technicians a clear connection style to verify against the existing fuse holder or equipment.
