APPLICATIONS
CJX1 (3TF) series AC contactors are suitable for frequency 50/60Hz,rated insulation voltage up to1000V,rated operation current 9~475A under AC-3 duty. It is mainly used for making/breaking electric circuit at a long distance & for frequent starting/stopping & with thermal relay to com-pose a magnetic motor starter. The product conforms to IEC60947-4-1 standard.
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, three are no arc isolated panel in the le¡Ý32A 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¡Ü32A contactor also by installation rail.
