Sharaxaad Gaaban:

M4 taxane ah oo kiis wareegga wareegga ah, waa wareegga lagu dabaqi karo ee AC 50 / 60Hz, oo lagu qiimeeyay korantada dahaarka 690 V(M4-125 500V), oo lagu qiimeeyay danab shaqeynaya AC 690V ama ka hooseeya, lagu qiimeeyay hadda 12.5-1600A, si loo qaybiyo tamarta korantada iyo samaynta aan caadiga ahayn iyo jebinta wareegga xaalad caadi ah. Qalabka wareegga wareegga waxaa la siiyaa shaqada ka hortagga culeyska xad-dhaafka ah iyo wareegga gaaban iyo korantada. Xakamaynta wareegga wareegga waxay u hoggaansamaan heerka IEC60947-2. Xakamaynta wareegga wareegga ayaa ah labajibbaaran (In m = 250A ama ka sarreeya), wareegga xakamaynta ee qalabka ayaa laga soocaa wareegga ugu muhiimsan, uma baahna inuu furo daboolka wareegga wareegga marka la rakibo qalabka.
