LPS-RK-3SP - 3Amp Fuse

LPS-RK-3SP - 3Amp Fuse

A fuse can have the right amp rating and still be the wrong fuse for the job. That's why matching the complete specification matters. The Eaton Bussmann series LPS-RK-3SP is a 3A 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 manufacturer-listed response time of 10 seconds at 500%. When you select it correctly, install it with qualified electrical personnel, and operate it within its specified ratings, the LPS-RK-3SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 3A Class RK1 configuration: Combines a 3-amp rating with Class RK1 construction, providing key electrical identifiers for compatibility checks.
• Time-delay operation: Eaton specifies the LPS-RK-3SP as a time-delay fuse. Match this operating characteristic to the circuit and connected equipment requirements.
• Current-limiting fuse: The manufacturer identifies this model as current-limiting, another key specification to confirm when selecting a fuse.
• Dual-element construction: Uses Eaton's specified dual-element design.
• 600VAC / 300VDC ratings: Rated for applications requiring the corresponding AC or DC voltage, subject to the equipment's requirements.
• Ferrule End × ferrule end connection: Gives installers another physical detail to verify against the existing fuse holder and equipment.
• Non-indicating configuration: Eaton identifies the LPS-RK-3SP as non-indicating.
