Fuses for railway applications
Advantages
ETI’s Railway Fuses successfully combine two usually conflicting fuse requirements:
aa low operating joule integral, necessary for the protection of semiconductors,
aa low power dissipation, allowing for lower energy losses and thus lower operating costs, fol-
lowing the latest ecological trends.
These unique technical characteristics are achieved by a completely new design of the ceramic
body, a special construction developed on the basis of long standing expert knowledge, which
allows for significantly better cooling of the fuse.
The operation of fuses is especially adapted for railway applications, as they have improved
resistance to current cyclic loading, a phenomenon that causes unnecessary fuse operating in
these applications. This way, ETI’s Railway Fuses help decrease downtime significantly, leading to
further cost savings and improved efficiency.
The melting element inside Railway Fuses is made of silver, which makes them highly insensitive
to ageing processes.
ETI Railway fuse-links ensure short circuit protection from minimum breaking capacity (5 x In) up to
maximum breaking capacity 30kA d.c. at time constant 15ms.
Application
Protection of DC link and semiconductor devices (diodes, thyristors, GTO) in railway inverters.
Standards
ETI Railway Fuses comply with the IEC 60269-4 and IEC 60077-5 standards.

DB, S368 series fuses are available for the following voltage ratings:
aa 1 kV AC and 1 kV DC
aa 1,5 kV AC and 1,5 kV DC
aa 3 kV AC and 3 kV DC
aa 5 kV DC
This range of fuses covers all existing train line voltages of the European railway systems.
Features
aa Compact design
aa 4 different sizes
aa Fuses designed for 5 kV DC
aa Standards: UIC 550, EN 50163 and IEC 60077-5.
Applications
