Littelfuse’s Compact Cartridge Fuses

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

Littelfuse has shared that 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.

LittelfuseThe 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.

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 ([email protected]/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 provides reliable protection in extreme temperature environments.
  • The environmentally-friendly component is RoHS compliant, halogen-free, and 100% Pb-free.
