Overview
The CJX2-09~95 Series AC Contactor (hereinafter referred to as “contactor”) is suitable for the circuits with AC 50 Hz or 60 Hz, rated working voltage up to 660 V, rated working current up to 95 A when the rated working voltage is 380 V in AC-3 use category. The contactor can be used for long-distance making and breaking of circuits, and can be combined with appropriate thermal overload relays to form an electromagnetic starter to protect circuits that may be overloaded.
This product complies with the requirements of GB14048.4 and IEC60947-4-1.
Normal working conditions
1. Ambient air temperature: The average temperature within 24 hours shall not exceed +35°C at -5°C ~ +40°C.
2. Altitude: Not higher than 2,000 m.
3. Atmospheric conditions: The relative atmospheric humidity at the installation site shall not exceed 50% at +40°C. A higher relative humidity is allowed at a lower temperature, e.g. 90% humidity at 20°C. Special measures shall be taken for the occasional condensation due to the temperature change.
4. Contamination grade: Grade 3.
5. Installation category: III.
6. Installation conditions: The inclination between the installation surface and the vertical plane shall not be more than ±5°.
7. Impact vibration: The installation place shall have no significant shaking, impact and vibration.
8. Transportation and storage: The contactor shall not be subjected to severe collision and vibration during the transportation, and shall not be attacked by rain and snow during the transportation and storage. The contactor is suitable for the transportation and storage at a temperature between -25°C and +55°C, which can reach +70°C in a short time (within 24 h).
Model description
Technical parameters
1. See Table 1 for the main technical parameters of the contactor.
2. Contactor coil working voltage Us: AC 36 V, 110 V, 127 V, 220 V, and 380 V. Other specifications can be negotiated with the manufacturer.
3. Operation characteristics: Pull-in voltage 85% ~ 110% Us; release voltage 20% ~ 75% Us.
4. The contactor body has a pair of normally-open or normally-closed auxiliary contacts in specifications of 32 A and below, and a pair of normally-open and normally-closed auxiliary contacts 40 A and above. Moreover, up to 8 pairs of auxiliary contact groups (with various normally-open and normally-closed combinations) can be installed. See Table 2 for the basic parameters and performance of auxiliary contacts.
5. See Table 3 for the power consumption and energy efficiency grade of the contactor pull-in coil.
