Bonitron now offers optimal protection fusing solutions for AC drives and has established standard packages for 230 and 460 VAC drives rated at 150% nominal Hp for 60 seconds. The Bonitron drive fuse solutions include high speed, low peak, electronic fuses. Enclosed units with optional lockouts and disconnects or Backplate models available. The Bonitron fuse solutions may also include 3 phase, high joule, varistor boards. When the MOV's and the high-speed fuses are coordinated, the drive system has both over current protection and over voltage transient protection. Bonitron fuse solutions may optionally include fusing for the drive DC bus. DC bus fusing should be considered for drive systems which are connected to an external :
• Common bus power supply
• Line Regen module
• Power Dip Ride-Thru
• Unity power factor power supply
• Other drives for bus regenerative power sharing
• Any application where external/Remote fusing is desired or required
