LPS-RK-300SP - 300Amp Fuse

LPS-RK-300SP - 300Amp Fuse

When you're replacing a fuse in electrical equipment, 300 amps is only one piece of the puzzle. The fuse class, voltage, interrupting rating, operating characteristics, connection style, and physical size must match the application. The Eaton Bussmann series LPS-RK-300SP is a 300A 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 correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPS-RK-300SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 300A Class RK1 configuration: Combines a 300-amp rating with the Class RK1 designation, two essential specifications when confirming compatibility with existing equipment.
• Time-delay operation: Eaton identifies the LPS-RK-300SP as a time-delay fuse, an important operating characteristic to match against the equipment requirements.
• Current-limiting design: The manufacturer specifies current-limiting characteristics for this fuse, providing another key electrical parameter for proper selection.
• Dual-element construction: Uses the dual-element configuration Eaton specifies for this catalog number.
• 600VAC / 300VDC voltage ratings: Supports applications requiring the manufacturer's specified AC or DC voltage rating, subject to proper system and equipment compatibility.
• Blade end × blade end connection: Provides a straightforward physical characteristic to check when confirming form and fit.
• Non-indicating configuration: Eaton identifies this particular catalog number as non-indicating.

Where It Works Best

The Eaton Bussmann LPS-RK-300SP 300A Class RK1 fuse is intended for compatible electrical equipment requiring its particular combination of a 300A rating, 600VAC / 300VDC voltage ratings, Class RK1 configuration, time-delay operation, current-limiting characteristics, dual-element construction, and blade-end × blade-end connection. Its electrically isolated end cap is another manufacturer-specified characteristic worth confirming when matching the fuse to an existing application.
