Caution: Make sure to connect the power supply, motor and switch correctly, according to each model and application. Please note that the push button switch and the control switch cannot be used simultaneously in the above connection diagrams.

Precautions For Using This Product

  • 1.The rated current of the thermal relay should be adjusted by rotating the knob to properly match the rated current of the motor to be used. The thermal relay rated current is set to the median value at the time of shipment.
  • 2.The startup time is set to 10 seconds for up to 22 kW (ADMT 220/ADMU 220), and 20 seconds for anything above that (ADMT 300 or higher/ADMU 300 or higher). Please adjust the time knob to set a suitable startup time depending on motor load conditions.
  • 3.Avoid inching and frequent, repetitive start/stop operation, as doing so will greatly reduce the electrical service life of electromagnetic contactors.
  • 4.The 3-contactor method (ADMT) completely shuts off the power supply via the electromagnetic contactors, making it ideal for starting motors for which operation is suspended for long periods of time, such as fire-fighting equipment, HVAC equipment and agricultural equipment, etc.
  • 5.In the dual-contactor method (SDMU), voltage is applied to the motor coil terminals even in the open circuit (OFF) state. To ensure safety when inspecting the motor or suspending the motor for long periods of time, open the switch installed on the power supply side of the device.
