Application:
- Industrial motors: JD-5 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 pumps and water treatment systems: In water supply systems, water pumps and water treatment equipment, JD-5 can ensure that the pump's motor is not overloaded or lost 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, the JD-5 can ensure that the compressor operates under rated load and does not suffer from phase loss.
- Application in construction: JD-5 can also be used in construction applications, such as in building and infrastructure construction projects where it is necessary to protect the engine from overloads and phase loss.
