Arresters for Ignition Voltages Of 1.5 Kv

The new lightning current arrester Flashtrab FLT PlusCTRL from Phoenix Contact with arc-chopping spark gap and additional ignition electronics limits surge voltages reliably to a maximum of 1.5 kV. This way, even surge voltages rich in energy in a protection device are limited to the protection level required for subsidiary distributions and circuit cables. Now, protection concepts, which require the use of lightning current arresters due to accordingly high danger potentials, can be designed in two protection levels instead of in three protection levels so far-the traditional second protection level Middle Protection is dropped. At the same time, the new protection device autonomously quenches line follow currents, even in power supply networks with very high short-circuit power. The distinct behavior of the arc spark gap as Current Brake ensures a low line follow current. The advantage of this technology is that fuses, even those with low rated values, are not released by the line follow current-which is especially important for systems with low connection values or with small input fuses. For specific applications, the ignition voltage can be individually preset by Phoenix Contact.
