Product Description

CJ20 AC Contactor
Scope of application:
CJ20 series AC contactor is suitable for the power system of AC 50Hz or 60Hz, rated working voltage up to 660V or 1140V and rated working current up to 630A, used to make and break circuit frequently in a far distance, while, it can be combined with thermal relay or electronic protection equipment to form into an electromagnetic starter, to protect the circuit against possible overload.
The products are in conformity with such standards as GB 14048.4 and IEC 60947-4-1.
Normal working conditions and installation conditions:
1. The altitude of installation sites do not exceed 2000m;
2. Ambient air temperature does not exceed 40 degrees Celsius, and the average
Temperature within 24h does not exceed 35 degrees Celsius; Minimum ambient air
Temperature is -5 degrees Celsius;
3. The air relative humidity of installation sites does not exceed 50% at a maximum
Temperature of 40 degrees Celsius; While can be allowed to have higher relative
Humidity at a lower temperature, such as to reach 90% at 20 degree Celsius.
Special measures should be taken to solve the occasional condensation due to
Temperature changes.
4. The tilt with the vertical is not more than 5 degrees; Mine starter is composed of
The contact mounting surface, and the tilt with the vertical is not more than 15 degrees.
5. Pollution degree: 3 degrees.
6. No significant shake, shock and vibration.
Structural features:
CJ20 series AC contactor is double power-down and direct acting structure with a layout
Of frontal installation and three-dimensional. The classes below 40A adopt "E" shaped iron core. The classes below
63A adopt "U"shaped iron core. Moving contacts are boat shape, and the static contacts
Adapt profiles, and fitted with iron arc angle.
The circuit basic parameters of contactor are shown in Table 1 and Table 2
The contact type, quantity, and its technical parameters of auxiliary circuit are shown in Table 3.
The basic parameters of contact main circuit are shown in Table 4.
Shape and installation dimensions:
1. The contactor is installed with screws. CJ20-10 ~ 25 can also be installed with 35mm
Standard rail.

We also produce many various of contactors.
