As an important control component in motor circuits, AC contactors play a crucial role in industrial production. Lightning strikesThe voltage drop (oscillation) phenomenon caused by short circuit reclosing, power grid faults, and high-power equipment start-up seriously affects the contactThe normal operation of the device and the shutdown of related interlocking equipment have caused huge economic losses to the enterprise.AcrelARD-KHD-S03Series anti vibration device, equipped with "vibration retention+The function of "shaking and restarting" canResist contactor release caused by shaking of the contactor control circuit (excluding DC contactors or contactors with energy-saving functions),It is also possible to achieve restart for frequency conversion and soft start circuits to ensure the continuous operation of equipment and safeguard the efficient production of enterprises.
