Tá bréasálaí cáis plastic leathnaithe chun úsáid i gcás comhréire 50Hz nó 60Hz.
Is féidir linn an cineál seo scagaire a chruthú le voltas ranga níos lú ná 1kV agus cosc ranga 800A agus níos ísle.
Tá sé ag críochnú cosaint iomlán, measúnú uasail, seoladh agus comhráil, agus tá sé go soiléir faoi mhéid.
Úsáidfear an t-athrú seo go príomha i bhfoghlaim níos lú níos íseal, bídeanna scagtha, agus eileacht níos íseal, mar sin freisin i ngéarchumas nua-energía.
Níor comhlíonadh na hábharlann
GB/T 14048 Scagaire agus riailithe low voltage
IEC 60947-2 Scagaire agus riailithe low voltage
