Littelfuse offers what it’s calling the smallest cartridge fuse series available that’s rated at 500 Vac with current ratings from 40A to 63A and a 2 kA at 500 Vac interrupting rating. The 606 Series Cartridge Fuse is designed for overcurrent protection in applications such as high voltage power supply circuits rated up to 23 kW. With a 10 mm x 32 mm cartridge body, a single 606 fuse requires less board space than previous designs that used multiple lower current rated fuses in parallel. Applications include:
- Telecom Uninterruptible Power Supplies (UPSs)
- Power conversion equipment such as inverters and rectifiers
- Electric Vehicle Supply Equipment (EVSE)
- Off-board charging posts
- Motor protection in elevator systems
Other features include end caps with integrated stand-off leads eliminate the need for mounting accessories and/or lead-forming processes and an operating temperature range from -55˚C to 125˚C. More information and specs are available on the 606 Series product page and from the 606 Series datasheet.
