LPS-RK-150SP - 150Amp Fuse

LPS-RK-150SP - 150Amp Fuse

When you're matching a 150A fuse, amperage is only the beginning. The Eaton Bussmann series LPS-RK-150SP is a 150A 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 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-150SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 150A Class RK1 configuration: Combines a 150-amp rating with the manufacturer's specified Class RK1 construction for accurate application matching.
• Time-delay operation: Eaton identifies this model as a time-delay fuse, making its operating characteristic an important part of compatibility checks.
• Current-limiting design: Eaton specifies the LPS-RK-150SP as a current-limiting fuse.
• Dual-element construction: Provides another manufacturer-defined characteristic to verify when selecting a fuse for existing equipment.
• 600VAC and 300VDC voltage ratings: Clearly defined AC and DC ratings help technicians determine whether the fuse matches the intended circuit.
• Blade end × blade end connection: An important physical detail when checking fit with compatible fuse holders and electrical equipment.
• Non-indicating configuration: Eaton identifies this catalog number as a non-indicating fuse.
