LPS-RK-80SP - 80Amp Fuse

LPS-RK-80SP - 80Amp Fuse

Choosing the right fuse is about more than matching the amp rating. The Eaton Bussmann series LPS-RK-80SP is an 80A 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, along with dual-element construction and a blade-end × blade-end connection. When properly selected, installed by your qualified electrical personnel, and operated within its specified ratings, this fuse is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 80A Class RK1 configuration: Combines an 80-amp rating with the Class RK1 designation, giving you two critical specifications to confirm when matching a fuse to existing equipment.
• Time-delay operation: Eaton identifies the LPS-RK-80SP as a time-delay fuse. Match this characteristic to the circuit's protection requirements.
• Current-limiting design: The manufacturer specifies current-limiting operation as part of the fuse's protective characteristics.
• Dual-element construction: Eaton lists this model as dual-element, another useful specification when identifying the correct fuse for an application.
• 600VAC / 300VDC ratings: Suitable for compatible equipment requiring the stated AC or DC voltage rating.
• Blade-end × blade-end connection: A key physical characteristic to verify against the existing fuse holder and equipment.
• Non-indicating configuration: Eaton identifies this catalog number as non-indicating.
