DCM621JN:Energy-Saving Holding Contactor Non-Release Type Anti-Sag Device

No.003

1. An anti‑voltage sag device specially designed for energy-saving contactors.

2. After the contactor releases due to voltage sag, this device can re‑engage the contactor to restore the motor to normal operation.

3. When a voltage sag occurs, the device is powered by its internal supercapacitor to maintain normal operation. Once the device detects the recovery of the power supply voltage, it closes its internal control node and transmits a restart command to the control loop, enabling the contactor to return to the engaged state and the motor to resume normal operation.

4. Compact size,126mm*66mm*102mm.

5. Rail-mounted for easy installation.
