Compact Cartridge Fuses with High-Current, High-Voltage Ratings

February 2, 2022

Littelfuse, Inc. (NASDAQ: LFUS), a global manufacturer of leading technologies in circuit protection, power control, and sensing, today announced the compact cartridge fuse series available that’s rated at 500Vac/Vdc with current ratings from 40A to 63A and a 10,000A interrupting rating.  The 607 Series high-current, high-voltage cartridge fuse, designed for overcurrent protection applications, provides a robust solution for demanding high-voltage power supply circuits. The 500V fuse rating is suitable for both AC and DC inputs. With a 10mm x 32mm cartridge body, a single 607 fuse requires less board space than previous designs that used multiple lower current rated fuses in parallel. As a result, designers can reduce the board space they reserve for protection components when designing high wattage equipment. View the video. Typical applications for 607 Series High-current Cartridge Fuses include:

  • Datacenter
  • Telecom
  • EV Charging
  • HVAC systems
  • Uninterruptable Power Supply (UPS)
  • Inverters and rectifier

“Today’s power designers need greater layout flexibility to help reduce the size of their high-wattage designs while increasing reliability,” said Style Liu, Global Product Manager, Electronics Business Unit at Littelfuse. “Not only does the 607 series offer a very compact footprint that saves board space, but also offers a very high interrupt rating and a high current rating when compared to similar fuses on the market.”
