CJX2 series AC contactors (hereinafter referred to as contactors) are mainly used in circuits with AC 50Hz or 60Hz, voltage up to 690V, rated working current up to 95A under AC-3, 400 (380)V use categories, for remote connection and disconnection of circuits, frequent starting and control of AC motors, and can be used with appropriate thermal relays to form electromagnetic starters to protect circuits that may be overloaded.
Compliance: GB/T14048.4, IEC 60947-4-1.
Working conditions and installation
● Ambient temperature: -5℃~+40℃, the average value within 24 hours does not exceed +35℃;
● Altitude: no more than 2,000m;
● Atmospheric conditions: When the maximum temperature is +40℃, the relative humidity of the air shall not exceed 50%; higher relative humidity can be allowed at lower temperatures, such as 90% at 20℃. Special measures should be taken for occasional condensation due to temperature changes;
● Pollution level: 3;
● Installation category: Category III;
● Installation conditions: The inclination between the installation surface and the vertical surface shall not exceed ±5°;
● Impact and vibration: The product should be installed and used in a place without significant shaking, impact and vibration.
