LPN-RK-350SP - 350 Amp Fuse Description

LPN-RK-350SP - 350 Amp Fuse

When you're matching a 350A fuse to existing electrical equipment, the label number is only the starting point. The Eaton Bussmann series LPN-RK-350SP is a 350A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 250VDC. Eaton specifies interrupting ratings of 300 kAIC at 250VAC and 100 kAIC at 250VDC, 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 LPN-RK-350SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

  • 350A Class RK1 configuration: Provides the specific amperage and fuse-class combination needed when matching compatible electrical equipment.
  • 250VAC and 250VDC ratings: Eaton specifies the fuse for both AC and DC applications at the stated voltage ratings.
  • Time-delay operation: The manufacturer identifies the LPN-RK-350SP as a time-delay fuse, an important characteristic to verify when matching a circuit's protection requirements.
  • Current-limiting fuse: Eaton classifies this model as current-limiting.
  • Dual-element construction: Uses the dual-element configuration specified for this particular LPN-RK fuse.
  • Blade end × blade end connection: Gives maintenance personnel a defined connection style to compare with the existing fuse and equipment.
