Application:
- Industrial motors: The JD-8 can be used to protect AC motors in industrial applications such as manufacturing machinery, presses, industrial water pumps, and other equipment. The overload function will prevent overload operation of the motor, which extends the service life and reduces the risk of failure.
- Water pumping and water treatment system: In water supply systems, water pumps and water treatment equipment, JD-8 can ensure that the pump's motor is not overloaded or lose phase, which helps maintain stable operating performance.
- Air conditioning system: In air conditioning systems and ventilation fans, this product can ensure that the motor operates within the safe current range and is not affected by phase loss.
- Air compressor: In industrial compressor systems, JD-8 can ensure that the compressor operates under rated load and does not lose phase.
- Construction applications: The JD-8 can also be used in construction applications, such as in building and infrastructure construction projects where it is necessary to protect the engine from overload and phase loss.
