235-16 Storm Trapper H.E. (High Energy) Low-Voltage
The surge arrester is designed such that the response surge voltage in the case of a voltage rise of 1 kV/μs is less than 2.2 times the nominal response DC voltage and predetermined parameters of the central electrode and of one of the side electrodes are identical.... VariSTAR Storm Trapper secondary class MOV surge arrester is designed to provide overvoltage protection for low voltage equipment and distribution circuits Type L secondary arresters protect street-lighting controls, low-voltage relays, railroad-signal circuits and circuits used for fire alarms, remote metering and airport lighting
Surge Arrestor & Grounding Baseline Systems
appropriate surge protective device for low-voltage systems connected to an overhead line. For a typical surge protection application an appropriate EMTP model is devised. The energy overload is calculated for a surge protective device following a simulation of the lightning effect. This way it is possible to determine the required class for the surge protective device in question. The... NU6 Low-voltage Surge Arrester NU6-!` 1.

- of the arrester. This low-voltage arc maintains equipment protection. Once an arrester has safely vented, it no longer possesses its pressure relief/fault current capability and should be replaced immediately. For a given application, the arrester selected should have a pressure/fault current capability greater than maximum short-circuit current available at the intended arrester location
