Contactor part number 1089941561

Atlas Copco contactor part number 1089941561 is a genuine original electrical control core component specifically designed for the GA series screw air compressors, precisely compatible with the electrical control system of GA models. As a key actuating element in the electrical circuit of GA models, this contactor primarily undertakes multiple critical functions: first, it enables the switching on and off of circuits for high-power electrical equipment such as the main motor and fan motor of the air compressor based on control system commands, ensuring that the equipment starts, operates, and shuts down as required; second, through reliable contact and breaking of internal contacts, it stably transmits electrical energy, ensuring continuous and stable power supply to electrical equipment and preventing operational abnormalities caused by poor circuit contact; third, it features basic protection characteristics such as overload and undervoltage, promptly breaking the circuit under abnormal conditions to reduce damage to the electrical components of the equipment.
As a genuine original part, the production of this contactor strictly follows Atlas Copco's high-standard quality system. It utilizes high-conductivity copper contacts and arc-resistant, high-temperature-resistant insulating materials, offering excellent electrical performance and mechanical durability to meet the operational demands of frequent starts and stops as well as continuous operation of GA models. Its installation dimensions and electrical parameters fully match the control cabinet layout and circuit design of GA models, allowing precise connection without the need for additional circuit modifications or adjustments to the installation structure, ensuring compatibility and synergy with the entire machine's electrical system. Through pre-delivery electrical performance tests, durability tests, and reliability verifications conducted by the original manufacturer, this contactor provides stable and reliable electrical control assurance for the GA series air compressors, helping to maintain safe and efficient operational conditions and extend the service life of the electrical system.
