3tf series ac contactors are suitable in electrical system with ac 50/60hz, rated operational voltage up to 660v, in ac-3 usage, rated operational voltage up to 380v, rated operational current up to 630a to make or break remote motors or system. they can form electromagnetic starters with suitable thermal overload relays 3ua series to protect system and motors against overload or phase-failure. they are made according to iec947-2, bs5424 & vde0660. the contactor is a straight motion mechanism having double-breaking contacts. the auxiliary contacts are arranged 2no, 2nc at most. it is employed the flexible locking connection between the contact support and core. there are no arc-isolated panel in the le=32a contactors, there are moulded arc-chute with arc-isolated panel. because all contacts are made of high non-fusibility and against corrosion silver alloy. all series products can be mounted by screws, le<=32a contactor also by installation rail. aeg mcb unelec c45 mcb aeg bkn dx mcb aeg aeg mcb unelec c45 nc-100h bkp bkh bkn bkm dx bh bh-p bh-n mg ge aeg pls6 l7 c65 dz47 dpn ,c60n, my my mw w40 bh-d6 k101 dpx mb h6 s250 e4cb 5sx 5su mem sx1-g3 sx2-g3 tql tqc bhc fn nf cm1 dz15 dz10 dz47le dpnle f360 id nfin +86-13757778950 lc1-d,3tb,3tf rccb,rcbo,rcd, meter, kwh meter, dd28, dd862 3ua nt-50 lg ls nf-cw,3vl,dpx,ns-100n,ne-100,s ,series,tseries,y,hfd,hhb,abs,sa,ea,am8,abs-d mccb miniature circuit breaker, dz47, c45, mcb, mccb, miniature circuit breaker, dz47le, c65, c45n, c16, c10, c25 specializing in producing mem, merlin gerin, lg, f&g, legrand models circuit breakers, and gmc, lc1-d and airconditioner ac contactors, and le1-d, ads7 magnetic starters and metal distribution boxes.
