CHICAGO — Littelfuse, Inc. introduced the smallest cartridge fuse series available that’s rated at 500VAC with current ratings from 40A to 63A and a 2,000A@500VAC interrupting rating. The 606 Series high-current Cartridge Fuse is designed for overcurrent protection in applications such as high-voltage power supply circuits rated up to 23kW. With a 10mm x 32mm cartridge body, a single 606 fuse requires less board space than previous designs that used multiple lower current rated fuses in parallel. As a result, designers can reduce the amount of board space they reserve for protection components when designing high-wattage equipment.
Typical applications for606 Series High-current Cartridge Fuses 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
The 606 Series High-current Cartridge Fuses offer these key benefits:
The smallest available 500VAC-rated cartridge fuse series with current ratings from 40A to 63A and a 2,000A@500VAC interrupting rating.
Suitable for overcurrent protection in a single-phase power supply circuit rated up to 23kW.
End caps with integrated stand-off leads eliminate the need for mounting accessories and/or lead-forming processes.
With an operating temperature range from -55˚C to 125˚C, these fuses can provide reliable protection in extreme temperature environments.
The 606 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.
