Ac contactor
CJX2-6511 AC contactor
Applicable Scope
CJX2 series AC contactors (hereinafter referred to as contactors) are mainly used in circuits with AC 50Hz (or 60Hz), voltage up to 690V, and current up to 95A. They are used for remote connection and disconnection of circuits, frequent starting and control of AC motors, and can be combined with appropriate thermal relays to form electromagnetic starters to protect circuits that may be overloaded.
The contactor complies with the standards: GB/T 14048.4, IEC60947-4-1.
Normal working and installation conditions
1. The ambient air temperature is: -5℃+40℃, and its average value within 24 hours does not exceed +35℃.
2. Altitude: no more than 2000m.
3. Atmospheric conditions: When the maximum temperature is +40°C, the relative humidity of the air does not exceed 50%; higher relative humidity is allowed at lower temperatures, such as 90% at 20°C. Special measures should be taken against occasional condensation due to temperature changes.
4. Pollution level: Level 3.
5. Installation category: Category III.
6. Installation conditions: The inclination between the installation surface and the vertical surface is not greater than ±5°.
7. Shock and vibration: The product should be installed and used in a place without significant shaking, impact and vibration.
