AC Contactor

Our AC contactor is an electrically controlled switch mainly used to control circuit or switch the power. It is widely used in electric motors, lighting devices, heating equipment, capacitor banks, and other electrical load control devices.

We have several modes of contactors for your consideration, that is, electromagnetic contactors, vacuum contactors, to name a few.

CJX1 (3TB, 3TD) Series AC Contactor

Our CJX1 (3TB, 3TD) series AC contactor can be used in electrical system with AC 50/60Hz and rated operational voltage up to 660V. With a suitable thermal overload relay, our AC contactor also can be an electromagnetic starter.

Features of CJX1 (3TB, 3TD) Series AC Contactor
1. Our AC contactor is a straight motion mechanism. It can be equipped with two breaking contacts. The auxiliary contacts are arranged with 2NO, 2NC at most.
2. Our AC contactor is made of high non-fusibility and against corrosion silver alloy. So there is no arc-isolated panel in the le≤22A contactors. There only has moulded arc-chute with arc-isolated panel in the Ie≥32A contactors.
3. Our AC contactor uses flexible locking connection to connect contact support and core.

Applications of CJX1 (3TB, 3TD) Series AC Contactor
Our contactor is suitable for circuits with rated voltage up to 660V, AC 50Hz or 60Hz, and rated current 630A. Both 3TD and 3TB series products quite meet the technical specifications of IEC947-2 and VDE0660.
