Littelfuse Offers Compact Cartridge Fuses Available with High-Current, High-Voltage Ratings

Compact cartridge fuses save circuit board space in high wattage equipment designs for use in  data centers, telecom, and HVAC applications.

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.”

The 607 Series High-current Cartridge Fuses offer these key benefits:

  • The compact cartridge fuse series is available with a high 500V rating for both AC and DC, and current ratings from 40A to 63A.
  • High interrupting rating (10KA@500Vac/500Vdc) provides a solution for dual voltage source power supplies suitable for a wide variety of applications.
  • End caps with integrated stand-off leads eliminate the need for mounting accessories or lead-forming processes.
  • Operating temperatures range from -55˚C to 125˚C providing reliable protection in extreme temperature environments.
  • The environmentally-friendly component is RoHS compliant, halogen-free, and 100% Pb-free.
