LPN-RK-20SP - 20 Amp Fuse

LPN-RK-20SP - 20 Amp Fuse

Getting the right fuse means checking more than the amperage printed on the label. The Eaton Bussmann series LPN-RK-20SP is a 20A 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-20SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 20A Class RK1 configuration: Combines a 20-amp rating with the Class RK1 designation for equipment requiring these specific fuse characteristics.
• 250VAC / 125VDC voltage ratings: Separate AC and DC ratings provide important information when matching the fuse to the circuit.
• Time-delay operation: Eaton specifies time-delay characteristics for the LPN-RK-20SP, an important consideration for applications that require this operating characteristic.
• Current-limiting design: Eaton identifies the fuse as current-limiting, another key specification to verify during fuse selection.
• Dual-element construction: Uses the manufacturer's specified dual-element configuration.
• Ferrule End × ferrule end connection: Gives electricians and maintenance personnel another physical characteristic to confirm when matching the fuse to existing equipment.
• Non-indicating configuration: Eaton identifies the LPN-RK-20SP as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPN-RK-20SP 20A Class RK1 fuse is intended for compatible electrical equipment requiring its combination of a 20A rating, 250VAC / 125VDC voltage ratings, time-delay operation, current-limiting characteristics, dual-element construction, and ferrule-end × ferrule-end connection. Eaton's stated high in-rush current motor protection is also relevant when evaluating this fuse for compatible motor applications.
