Kukhazikitsa kosavuta ndikubwezeretsanso chifukwa chakapangidwe kakang'ono ka malo ochepa (m'lifupi mwa 18/36 mm)
Chipangizo chotetezera chophatikizira chamitengo ingapo, chida chodzitchinjiriza, malo omangidwa amaphatikizira mayankho poteteza machitidwe mpaka 440 V ac motsutsana ndi mafunde omwe amayamba chifukwa cha kutulutsa kwamlengalenga ndikusintha ntchito.
- - Chipangizo cha AC Surge Protector T2 / Mtundu 2 / Class C / Class II
- - Makonzedwe amtundu wa AC (Gawo limodzi / 3-Gawo)
- - Kutulutsa mafunde (Iimp, Imax, In)
- - Chitetezo chaukadaulo (varistors, GDT)
- - Zinthu (plug-in, signature yakutali, yaying'ono, kapangidwe kakang'ono ka malo ochepa)
Chida chotetezera chophatikizira chamitengo ingapo, SPD, chida choteteza chitetezo, chowombera SLP40K mndandanda ndi gulu la Zipangizo Zamtundu wa 2 T2 Class C Zoteteza. Amapangidwa kuti azitchinjiriza kutchinga kwakanthawi komwe kumachitika chifukwa chosintha mwachangu kapena kugunda kwamphamvu kwa mphezi (zotsatira zotsalira).
Ndikulimbikitsidwa kukhazikitsa Class II SPDs iliyonse 10 - 20 metres kutalika kwa chingwe mobwerezabwereza, makamaka kuma board akulu ndikugawa. SLP40K-440 idapangidwa kuti igwirizane mwachindunji ndi Class I SPDs ya mzere FLP25. Pankhani ya SLP40K-275, kulumikizana ndi mzere FLP25 kumachitika pogwiritsa ntchito chingwe cha 10 m kutalika.
Kapangidwe ka AC Surge Protective Device T2 kutengera Metal Oxide Varistors. Kupanga koteroko kumapereka nthawi yotsika kwambiri. Kapangidwe kazomwe zimayikika ndi ma plug-in amalola kusintha kosavuta komanso mwachangu kwa ma module amachitidwe ngati MOV itha kupitirira ngati utali wamoyo wake chifukwa chakuchuluka kwazitali zazitali.
