The new HIGH SPEED RK1 (HSRK) combines semiconductor fuse performance with NEC branch circuit compliance. The fuse was designed with two specific applications in mind:

• To provide semiconductor fuse performance to solid state drive applications but in the larger RK body sizes that have been typically installed in older systems.
• To provide industrial power applications with the most current limiting fuse available, which in turn provides the best arc flash mitigation available to power systems using the larger RK size fuses.
  
  

FEATURES:

• Most current limiting RK1 available
• Provides the best Arc flash mitigation for feeder and branch circuits (non motor load circuits)
• Excellent cycling ability for frequent drive starts and stops without nuisance opening
• Extremely Low I2t

APPLICATIONS:

• Branch circuits
• AC drives
• Solid state controllers
• Feeder circuits
• Arc flash mitigation
