With the 3EL5 surge arrester, Siemens’ many years of extensive experience in the station class is now also available for the intermediate class. The 3EL5 is the first choice for all protection tasks with more demanding requirements for arresters. These could involve the safety of nearby systems, for example, or moisture ingress. The metal oxide blocks of the arrester are held in position by prestressed FRP rods, which prevent ejection of parts in the event of an overvoltage. At the same time, the electric arc can escape thanks to the flexible silicone housing vulcanized directly onto the active part. As a result, there is no buildup of high pressure inside the arrester. The use of a special silicone as insulation also permanently prevents moisture from penetrating, and the silicone sheathing retains its water- and dirt-repellent properties even after decades of use. The arresters in this robust, reliable series are suitable for all applications up to 60 kV. 3 mounting holes bolt circle 7.87–10 in for grounded installation (insulated installation on request) Voltage per unit MCOV*) 1.7 1.6 3EL5 intermediate, no prior duty, preheated to 60 °C 1.5 3EL5 intermediate, prior duty, preheated to 60 °C 1.4 Installation and Grounding 3EL5 1.3 1.2 1.1 1 0.01 0.1 1 10 100 1000 10000 Time in seconds *) Minimum guaranteed values, the specific values for TOV capability can be found in the table on the back page.
