ESKA bietet SMD-Sicherungen und SMT-Sicherungen für IT-/Netzwerktechnik und Datacenter.

IT / Network Technology

Due to the increasing number of computers, laptops and smartphones global demand for IT infrastructure has risen steeply.

To cover this demand, many small and big computer centers are being established. Irrespective of the data centers’ field of application – safety of computer systems is an investment that will be paid back, because each time a fuse opens follow-up costs due to long and expensive downtimes have been avoided. ESKA provides the respective customers with the necessary fuses. New requirements of this industrial sector are increasingly used DC voltages in computer centers to considerably reduce the number of power supply units.


250 V AC up to 420 V DC
≥ 100 mA
Breaking capacity:
Up to approximately 300 A in the case of upstream power supplies with limited short-circuit current rating. Up to 1.500 A also possible, if no power supply is installed upstream.
Product requirements:
More and more data centers use direct current to supply servers etc. with power. Thus, several power supplies can be saved and a central converter can be used for power supply. DC fuses are then installed in the individual paths as protection devices.
