Littelfuse has 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.

Availability The 607 Series High-current Cartridge Fuses are available in through-hole, 10mm x 32mm packages in trays in quantities of 500. Sample requests may be placed through authorized Littelfuse distributors worldwide. For a listing of Littelfuse distributors, please visit Littelfuse.com.
