JKS-50 - 50 Amp Fuse Description

JKS-50 - 50 Amp Fuse

Choosing the right fuse is about more than seeing 50A on the label. The Eaton Bussmann JKS-50 series provides clear specifications to match your equipment: a 50-amp rating, 600V rating, Class J configuration, and 200 kAIC interrupting rating at 600VAC. For maintenance, repair, or replacement work where the equipment specifically calls for these characteristics, the JKS-50 is built to last.

Key Features and Benefits

  • 50A current rating: Provides a precise amperage rating to match the fuse to compatible electrical equipment.
  • 600V rating: Clearly defined voltage rating makes specification checks straightforward.
  • Class J configuration: Designed for applications specifically requiring a Class J fuse.
  • Ferrule-to-ferrule connection: Uses ferrule end x ferrule end connections, giving you another important physical compatibility point to verify.
  • Single-element construction: Manufacturer specifications identify the JKS-50 as a single-element fuse.

Where It Works Best

The Eaton Bussmann JKS-50 suits compatible electrical equipment that requires a 50A, 600V Class J fuse with a 200 kAIC interrupting rating at 600VAC. Its single-element configuration, ferrule-to-ferrule connections, and 2.38 x 1 x 1-inch dimensions give technicians several specific points to compare with the existing fuse and equipment documentation.
