Robust 6.3×32 fuse for high power and inrush current requirements

New 6.3×32 mm ceramic fuse for single-phase applications for high rated currents from 10 A to 50 A. Thanks to a particularly high melting integral, it is particularly suitable for applications in which high inrush currents occur.

The new  SUT-H is technically based on the proven SUT. In contrast to the known fuse, the SUT-H has a much higher melting integral, which makes it particularly pulse resistant. High inrush currents, such as occur in power supply units, are therefore resisted without complaint.

The fuse is offered for direct mounting on the PCB with pigtails or with a solid beryllium-copper clip (SCHURTER CQP), which allows an easy replacement of the fuse without soldering. The clip can be operated up to 30 A, which is much more than a standard tinned clip, which can normally only be used up to a rated current of 10 A.
