CJX2 115-780 Series (AC Contactor)

The CJX2 series AC contactor is engineered for deployment in AC circuits with frequencies of 50Hz or 60Hz, boasting a rated operational voltage of up to 690V and a rated operational current of up to 780A.

Its primary function is to enable remote control of circuit connection and disconnection, facilitating safe and convenient on/off operations for electrical systems. Additionally, the contactor can be integrated with a thermal relay to form an electromagnetic starter, which delivers reliable overload protection for the connected circuit.

This product fully complies with the international standard IEC/EN 60947-4-1, ensuring adherence to global industry safety and performance benchmarks.

4.Magnetic system

Figure 1 General structure sketch map for CJX2-115~265 contactor

6.2 Contact system of the contactor is direct-acting, double breakpoint arrangement, the lower bastdopts the aluminum alloy material, the coil is the plastic sealing structure, and the coil is combined with a magnetic yoke into a whole, which can be directly taken out or placed in, it’s very convenient and maintenance. to see figure 1

6.3 There are one couple of NO contacts inside the coil of contactor, which can be used as auto-local contact or signal contact; Additionally, it can be attached to equip with two auxiliary contact groups total of 8 couples contacts, see map 2. Combination information of auxiliary contact to see table 2

6.4 Small arcing distance of contactor, for example, the arcing distance of CIX2-115-330 is nearly 10mm (200-500V), which is one-sixth of another same capacity contactor. It is used for complete equipment can reduce the usage space, and is an excellent supporting component in power electric control equipment

6.5 It can be attached the auxiliary contact group, air delay contact, and other accessory by building block type installation mode to see Figure 2

6.6 Contactor can be attached with horizontal or vertical mechanical interlock and reciprocal interlocletween two pcs of vertical installation contactor.
