65A Contactor for Carrier AC Unit

The high-quality 65A Contactor for Carrier AC Unit produced by SPX Electric Factory is an automatic switching device that uses electromagnetic principles to control circuits. It drives mechanical contact movements through small currents (coil electrification generates a magnetic field) to achieve the on-off of high current main circuits. Its core structure includes electromagnetic system (coil, iron core), contact system (main contact carries high current, auxiliary contact is used for control circuit), and arc extinguishing device (eliminates arc). Suitable for scenarios such as motor start stop, lighting control, industrial equipment power management, etc., it has the characteristics of safety and reliability, strong frequent operation ability, and isolation of high and low voltage circuits. It is a key executing component in automation control systems.

Wiring technique: Connect the normally open contact of the start button in parallel with the auxiliary normally open contact of the 65A Contactor for Carrier AC Unit, engage the contactor, and close the auxiliary normally open contact. By continuously supplying power to the coil through its own auxiliary normally open point, self-locking is formed. Pressing the red stop button causes the contactor to lose power.

Installation and maintenance

Before installation, the inspection needs to confirm whether the technical data of the customized 65A Contactor for Carrier AC Unit meets the standards, such as rated voltage, current, operating frequency, etc. It is also necessary to check whether the appearance is damaged, whether the action is flexible, and measure the DC resistance value and insulation resistance value of the coil. The installation position should be vertical, with an inclination of no more than 5 °, and one side of the heat dissipation hole should face in the vertical direction. When installing wiring, avoid parts such as screws, washers, and connectors falling off, which may cause the AC contactor to get stuck or short circuit. After installation, it is necessary to check whether the wiring is correct. When the main contact is not electrified, it should be powered on and off several times to check whether there is noise after the action of the main contact and the attraction of the iron core. Only after confirming that there is no error can it be put into use. It is not allowed to connect the AC contactor to the DC power supply, otherwise it will burn the coil
