Typical applications

Protection startup mode

After the device is activated, DO3 closes and the start button SB2 is pressed. KM1 coil is powered on, and the motor starts. When a fault trips, DO3 disconnects, KM1 coil loses power, and the motor stops. Press SB1 to stop

Direct startup mode

Bidirectional startup mode

Bidirectional quick action mode

Resistance voltage reduction starting method

Star delta relay starting method

Star delta relay open-loop starting method

Star delta relay closed-loop starting mode
