HD1 Series Single-Phase Motor Starter Control Box

After the compressor starts, the voltage across the relay coil increases as the compressor motor speed increases. When
When the motor speed reaches 70%~80% of the rated speed, the voltage on the coil generates an electromagnetic force that attracts the armature, causing the normally closed contact to open and the starting capacitor to lose its function. When the compressor is powered off, the normally closed contact automatically closes under the action of the spring, preparing for the compressor to restart.

The global HVACR relay market continues to grow.
