LPN-RK-150SP - 150 Amp Fuse

LPN-RK-150SP - 150 Amp Fuse

When you're matching a fuse to existing electrical equipment, the catalog number is only the beginning. The Eaton Bussmann series LPN-RK-150SP is a 150A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 250VDC. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPN-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 Class RK1 designation for compatible electrical equipment.
• 250VAC and 250VDC ratings: Suitable for applications requiring the manufacturer's specified AC or DC voltage rating.
• Time-delay operation: Designed with time-delay characteristics that should match the requirements of the circuit and connected equipment.
• Current-limiting fuse: Eaton identifies the LPN-RK-150SP as current-limiting, which is important when confirming the required fuse type.
• Dual-element construction: Uses two elements as specified by the manufacturer.
• Blade-end × blade-end connection: Provides an important physical checkpoint when confirming compatibility with existing equipment.
• Non-indicating configuration: Eaton identifies this catalog number as non-indicating.
