Current Limiting High-Speed Class J Drive Fuses

• JHL series high-speed fuses can be used with GS and DURAPULSE drives in non-UL applications. Fuse the drive according to NEC guidelines (NEC Article 430).
  
  
• For UL applications, GS and DURAPULSE drives require Class T fuses (refer to the drive’s user manual for details).

Current limiting, high-speed class J fuses start at $16.50each and are sold in 1 or 10 fuses per pack.

• Space saving Class J dimensions allow the use of readily available Class J fuse blocks, holders, and switches
