LPS-RK-90SP - 90Amp Fuse

LPS-RK-90SP - 90Amp Fuse

Choosing the right fuse means matching the details, not just the amperage. The Eaton Bussmann series LPS-RK-90SP is a 90A 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. When you select it correctly, install it with qualified electrical personnel, and operate it within its specified ratings, this fuse is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 90A Class RK1 configuration: The 90-amp rating and Class RK1 designation provide two essential identification points when matching a fuse to compatible equipment.
• Time-delay operation: Eaton specifies the LPS-RK-90SP as a time-delay fuse, making the fuse type an important consideration when confirming the required circuit protection.
• Current-limiting design: Eaton identifies this model as current-limiting, another electrical characteristic that should match the application requirements.
• Dual-element construction: Provides an additional specification to verify when replacing an existing fuse or working from equipment documentation.
• 600VAC / 300VDC rating: Supports applications designed around the manufacturer's stated AC or DC voltage ratings.
• Blade-end × blade-end connection: The blade-style connection is an important physical characteristic to check before installation.
• Non-indicating configuration: Eaton identifies this catalog number as non-indicating.

Where It Works Best

The Eaton Bussmann LPS-RK-90SP 90A Class RK1 fuse is intended for compatible electrical equipment that requires its specific combination of a 90A current rating, 600VAC or 300VDC voltage rating, time-delay operation, current-limiting characteristics, dual-element construction, and blade-end connections.
