Compact Tubular Fuse Saves Space on High-Power Equipment Congested Circuit Boards

Littelfuse Corporation today introduced the smallest series of tubular fuses available on the market. Its rated current is 40A to 63A when the AC voltage is 500V, and the breaking current is 2,000A when the AC voltage is 500V. With a 10mm x 32mm body, the board space required for a single 606 fuse is less than the design of many low-current-rated fuses in parallel. As a result, designers can reduce the amount of board space reserved for protecting components when designing high-power devices.

Typical applications for the 606 series high-current tubular fuses include:

Telecommunications Equipment Uninterrupted Power Supply (UPS)
Power conversion equipment such as inverters and rectifiers
Electric Vehicle Power Equipment (EVSE)
Non-vehicle charging pile
Motor protection for elevator systems

"The 606 series has a compact form factor that reduces the amount of space occupied by the protection components on the board, which gives designers of high-power devices greater layout flexibility." said Ben Zheng, Global Product Manager, Littelfuse Electronic Devices Business Unit. . "In addition to this advantage, compared to similar fuses from other suppliers, the rated breaking current is lower and the rated current is higher."

The 606 series high-current tubular fuses have the following key advantages:

The smallest 500V rated voltage tube fuse series on the market, rated current is 40A to 63A, rated voltage breaking current is 2,000A when AC voltage is 500V.
Suitable for overcurrent protection of single-phase power circuits rated up to 23kW.
End caps with integrated shedding leads eliminate the need for mounting accessories and/or lead forming processes.
This fuse has an operating temperature of -55 ̊C to 125 ̊C and provides reliable protection in extreme temperature environments.
