1 Elctronic Circuit Protctor ESX0-T.- Dscription Elctronic circuit protctor typ ESX0-T is dsignd to nsur slctiv disconnction of systms. Prliminary powr supplis, which ar widly usd in industry today, will shut down th output in th vnt of an ovr with th rsult that on faulty in th systm can lad to complt disconnction of all s. As wll as an unidntifid failur this also mans stoppag of th whol systm. Through slctiv disconnction th ESX0-T rsponds much fastr to ovr or short circuit conditions than th switch-mod powr supply. This is achivd by activ currnt limitation. Th ESX0-T limits th highst possibl currnt to.3 to.8 tims th slctd ratd currnt of th circuit protctor. Thus it is possibl to switch on capacitiv s of up to 20,000 μf, but thy ar disconnctd only in th vnt of an ovr or short circuit. For optimal alignmnt with th charactristics of th application th currnt rating of th ESX0-T can b slctd in fixd valus from 0. A...2 A or in adjustabl ratings 2 A/4 A/6 A. Failur and status indication ar providd by a multicolour LED and an intgral shortcircuit-proof status output or a potntial-fr signal contact. Rmot opration is possibl by mans of a rmot rst signal or a rmot ON/OFF control signal. Th manual ON/OFF button allows sparat actuation of individual circuits. Th ESX0-T, with a width of only 2. mm, can b snappd onto symmtrical rails nsuring as of installation and saving spac in control cabints. Upon dtction of ovr or short circuit in th circuit, th MOSFET of th output will b blockd to intrrupt th currnt flow. Th circuit can b r-activatd via th rmot lctronic rst input, control input or manually by mans of th ON/OFF button. Faturs Slctiv protction, lctronic trip charactristics. Activ currnt limitation for saf connction of capacitiv s up to 20,000 μf and on ovr/short circuit. Currnt ratings 0. A...2 A or adjustabl ratings 2 A/4 A/6 A. Rliabl ovr disconnction with. x I N plus, vn with long lins or small cabl cross sctions (s tabl 3). Manual ON/OFF button (S). Control input IN+ for rmot ON/OFF signal (option). Elctronic rst input RE (option). Clar status and failur indication through LED, status output SF or Si contact F. Intgral fail-saf lmnt adjustd to currnt rating. Width pr unit only 2. mm. Rail mounting Eas of wiring through busbar and 0 V as wll as signal bars and bridgs.
