LPS-RK-250SP - 250Amp Fuse

LPS-RK-250SP - 250Amp Fuse

Choosing the right 250A fuse takes more than matching the amp rating. The Eaton Bussmann series LPS-RK-250SP is a 250A Class RK1 time-delay, current-limiting fuse rated for 600VAC and 300VDC. Eaton specifies interrupting ratings of 300 kAIC at 600VAC and 100 kAIC at 300VDC, giving electricians and maintenance professionals clear electrical values to check against your equipment and circuit requirements. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPS-RK-250SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 250A Class RK1 configuration: Clearly identifies the amperage and fuse class to match compatible equipment requirements.
• Time-delay operation: Eaton specifies the LPS-RK-250SP as a time-delay fuse, an important operating characteristic to verify when selecting a replacement.
• Current-limiting fuse: The manufacturer-designated current-limiting construction is another key specification to confirm when selecting the correct circuit-protection device.
• Dual-element construction: Eaton identifies this model as a dual-element fuse.
• 600VAC and 300VDC ratings: Supports equipment requiring the manufacturer's specified AC or DC voltage rating.
• Blade-end × blade-end connection: Gives maintenance personnel a clear physical connection detail to verify before installation.
• Non-indicating configuration: Eaton identifies the LPS-RK-250SP as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPS-RK-250SP 250A Class RK1 fuse is intended for compatible electrical equipment requiring its particular combination of a 250A current rating, 600VAC / 300VDC voltage ratings, Class RK1 construction, time-delay operation, current-limiting characteristics, dual elements, and blade-end × blade-end connections. Its electrically isolated end cap is another manufacturer-listed characteristic to consider when matching the required fuse.
