Weidmullerndi katswiri pa kudula zingwe zamkuwa kapena aluminiyamu. Zogulitsa zimayambira pa odula ang'onoang'ono ang'onoang'ono omwe amagwiritsa ntchito mphamvu yachindunji mpaka odulira ma diameter akulu. Kugwira ntchito kwamakina ndi mawonekedwe ocheka opangidwa mwapadera amachepetsa kuyesetsa kofunikira.
Ndi mitundu yosiyanasiyana yodulira,Weidmullerimakwaniritsa zofunikira zonse zaukadaulo wama chingwe.
Zida zodulira ma conductor mpaka 8 mm, 12 mm, 14 mm ndi 22 mm kunja kwake. Geometry yapadera ya blade imalola kudula kopanda kutsina kwa ma conductor amkuwa ndi aluminiyamu ndikulimbitsa thupi. Zida zodulira zimabweranso ndi VDE ndi GS-zoyesedwa zodzitchinjiriza zoyeserera mpaka 1,000 V malinga ndi EN/IEC 60900.
