2 Gas Tube Aestes The Potection Poducts Goup of Wold Poducts Inc., specializing in potection poducts fo AC and DC cicuits, is poud to featue a full line of Gas Tube Aestes. Ceamic Gas Tube Aestes povide potection fo pesonnel, equipment and cicuity fom the abnomally high tansient voltages which can be caused by lightning o electomagnetic induction. The aestes ae designed with defined suge limiting chaacteistics. When the abnomal voltage on a line eaches that defined level, spakove (o beakdown) occus within the gas tube aeste, the suge is ediected and people and equipment ae potected. Ceamic Aestes ae vey duable and extemely gastight. They have pecise spakove voltages and vey high AC cuent withstand capability and impulse withstand capability. Diffeent applications equie diffeent types of aestes and WPI povides aestes to meet evey need. Aeste models vay both in dimension and in electical chaacteistics and it is impotant that aestes be selected in accodance with the equiements of the paticula application. While two electode aestes have the advantage of being lowe piced, the opening in the cente electode of the thee electode aeste allows the two gaps of the aeste to shae a common gas chambe. This causes spakove to occu almost simultaneously in both sides of the aeste and minimizes the cuent suge in the potected lines. The vaious standad designs ae descibed in this catalogue. Aestes fo special applications ae also available and we welcome you inquiies if the model you need is not listed hee. Discove why WPI is the fist choice in Gas Tube Aestes.

4 Fail Safe Device Pupose Gas Tube Aestes ae typically used to quickly and safely potect moden telecommunications equipment fom damage caused by tansient suge voltages. Lightning and equipment switching opeations ae two common causes of these shot duation suge voltages. Gas Tube Aeste opeation does not geneate any significant heat duing these events which nomally last a few micoseconds o less. Howeve, suge voltages can also be caused by cossove fom powe supply lines and last significantly longe. Gas Tube Opeation may continue fo extended peiods and geneate significant themal enegy. To pevent heat caused damage to the aeste magazine o the teminal block and to eliminate any possible fie hazad, a Gas Tube Aeste equipped with back-up shot cicuit mechanism known as a Fail-Safe Device may be employed. Opeation The Fail-Safe Device is a shot cicuit sping that is mounted on the cente electode of the Gas Tube Aeste. Pio to opeation, a solde pellet installed between the sping and the cente electode of the Gas Tube Aeste and thin insulating tubes coveing shap pojections at each end of the shot cicuit sping foce the Fail-Safe Device to "float" mm above the oute electodes of the Gas Tube Aeste. Befoe Opeation When polonged dischage opeation causes the tempeatue of the Gas Tube Aeste to ise to the melting point of the solde pellet, the shot cicuit sping moves close to the Gas Tube Aeste and its tension foces the pojections though the thin insulation making contact with both Gas Tube Aeste oute electodes. This pocess pemanently shot-cicuits all thee electodes ceating a low esistance path to gound that will conduct the fault cuent without geneating significant heat. Afte Opeation Fail-Safe Activation Time Fail-Safe Device Activation Times vay fom model to model. See the Gas Tube Aeste Specifications fo details. Installation Cae should be taken when installing Gas Tube Aestes equipped with Fail-Safe Devices into aeste magazines, pinted cicuit boads, etc. because too much downwad pessue may foce the shot cicuit sping pojections though the thin insulation ceating a shoted condition.
