Littelfuse Inc., a manufacturer of circuit protection, power control and sensing technology solutions, has launched a compact cartridge fuse series rated at 500 V AC/V DC with current ratings from 40 A to 63 A and a 10,000 A 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 500 V fuse rating is suitable for both AC and DC inputs. With a 10 mm x 32 mm cartridge body, a single 607 fuse requires less

Typical applications for 607 Series high-current cartridge fuses include:
- Datacenter
- Telecom
- Electric vehicle 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 500 V rating for both AC and DC, and current ratings from 40 A to 63 A.
- High interrupting rating (10 KA at 500 V AC/500 V DC) 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 temperature range from -55˚ C to 125˚ C provides reliable protection in extreme temperature environments.
- Environmentally friendly component that is RoHS compliant, halogen-free and 100% lead-free.
The 607 Series high-current cartridge fuses are available in through-hole, 10 mm x 32 mm packages in trays in quantities of 500. Sample requests may be placed through authorized Littelfuse distributors worldwide.
