LPS-RK-25SP - 25 Amp Fuse

LPS-RK-25SP - 25 Amp Fuse

When you're matching a replacement fuse, the 25A rating is only the starting point. The Eaton Bussmann series LPS-RK-25SP is a 25A Class RK1 time-delay, current-limiting fuse rated for 600VAC and 300VDC. Eaton specifies an interrupting rating of 300 kAIC at 600VAC and 100 kAIC at 300VDC, along with a 10-second response time at 500%. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPS-RK-25SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 25A Class RK1 configuration: Provides clear amperage and fuse-class specifications for matching the fuse to compatible equipment.
• Time-delay operation: Eaton identifies this model as time-delay, an important characteristic to check when replacing an existing fuse.
• Current-limiting design: Eaton specifies the LPS-RK-25SP as a current-limiting fuse.
• Dual-element construction: Uses the dual-element configuration Eaton specifies for this catalog number.
• 600VAC / 300VDC voltage ratings: Clearly defined AC and DC ratings make it easier to verify the fuse against the intended circuit.
• Ferrule-to-ferrule connection: An important physical detail when checking form and fit.
• Non-indicating configuration: Eaton identifies the LPS-RK-25SP as non-indicating.
