28 Fuses for TVSS products protection SRF Series Surge Fuse Through the past few years, the transient voltage surge suppresion (TVSS) industry has grown to one of the fastestgrowing segments among power protection products. Newness from ETI is series of fuses named SRF (Surge Rated Fuses), intended for the protection of TVSS products. The SRF Series has been designed to survive 8/0 μs or /350 μs lighting surge pulses without operating, allowing the TVSS system to react to the surge. Surge fuses have either 8/0 μs or /350 μs ratings, not a continuous current rating. These fuses are intended to be installed in series with the TVSS devices and do not normally carry current, except for the periodic random surges caused by TVSS breakdown during normal operation. Under AC short circuit conditions these SRF surge suppression fuses have extremely high capability for current limitation. Features / Benefits 00V a.c. (8/0 μs) or 00V a.c.

30 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 alow power, allowing for lower energy losses and thus lower operating costs, following 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. Protection of DC link and semiconductor devices (diodes, thyristors, GTO) in railway inverters. Standards ETI Railway Fuses comply with the IEC 09- and IEC standards.

58 Fuel Cell Fuses The characteristics of fuel cell fuses FCF are developed according to standard ISO to meet the needs of fuel cell protection. Fuse links are used in fuel cell applications up to the nominal voltage 50V d.c. and maximum breaking capacity 000A at time constant up to ms. Minimum breaking capacity is x at nominal voltage. Without the protection of the specially designed FCF, the high DC voltage could experience severe arcing, thermal incidents or other hazards in the event of the overload or short circuit on fuel cells. v The decign of FCF is based on DC fuses. It has been redesigned to fit the needs the fuel cell protection acc. to Standard ISO Fuel cell fuse-fcf is a reverse current protection device for a fuel cell of a power circuit and it protects the fuel cell from damage caused by reverse current into the fuel cell. : 50V d.c.
