Cov ntawv thov

Cov Khoom Siv Tam Sim No uas seem tawm hauv kev tiv thaiv, tiv thaiv hluav taws xob ntawm ircuit ntawm 50Hz lossis 60Hz, qhov ntsuas hluav taws xob ib theem 240V, 3 theem 415V, ntsuas tam sim no txog 63A. Thaum ib tug neeg raug hluav taws xob poob siab lossis cov tam sim no seem ntawm lub voj voog tshaj qhov nqi ruaj khov, RCD tuaj yeem txiav lub zog hauv lub sijhawm 0.1s tiv thaiv kev nyab xeeb ntawm tus kheej thiab tiv thaiv cov khoom siv ntawm qhov txhaum los ntawm cov tam sim no seem. Nrog rau qhov kev ua haujlwm no, RCD tuaj yeem tiv thaiv lub crcit tiv thaiv overload thiab luv luv circuit lossis tuaj yeem siv rau kev hloov pauv ntawm irtr hauv qab nom codin. Nws ua raws li IEC898-87 & IEC 755.
