Fuse Sustains High Currents

Jan. 10, 2019
SCHURTER's fuse has a high melting integral.

A 6.3 x 32 mm ceramic fuse with a rated current range from 10 to 50 A, the SUT-H, is particularly suited for applications with high inrush currents.


In contrast to the SUT, the SUT-H has a much higher melting integral, which makes it extremely pulse resistant to high inrush currents, as in providing absorption of such occurrences in power supply units. The fuse series also has a high breaking capacity up to 500 A @ 250 VAC, 10 kA @ 125 VAC.


The SUT-H is offered with axial leads for direct mounting on the PCB or without leads for insertion into solid beryllium-copper fuse clips, series CQP. The clips are rated for use up to 30 A, which is substantially higher than conventional tin-plated clips, which are often limited to a maximum operating current of 10 A.


The fuse opens completely new areas of application, due to the extended rated current range up to 50 A. It also provides for more compact innovative application designs. The fuse series meets the requirements of the UL 248-14 standard and is cURus approved and RoHS compliant.
