Mersen HSJ Fuses Provide Advanced Protection for VFDs

10/7/2020

Variable Frequency Drive manufacturers no longer include fuses inside their device to help protect their products. Without the protection of a fuse with your VFD, you run the risk of dealing with nuisance tripping or even outages. Mersen’s High Speed Class J fuse (HSJ) family is capable of providing NEC branch circuit protection and the protection of internal sensitive electronics. The HSJ family of fuses works to solve the problem associated with having a UL listed product for branch protection along with the speed to protect sensitive electronics internal to the drive. By using Mersen HSJ fuses the price of replacing costly equipment is essentially eliminated.
