NOTE:
1. Silver plating of copper bar for main circuit wiring;
2. Auxiliary contact wiring plate is silver plated by default;
3. The product coil adopts positive and negative pulse excitation, and the excitation time is 50ms≤ T ≤200ms.The coil shall not be continuously energized for long periods, the operating frequency shall not exceed 6 times per minute, and the pulse shall be square wave.Positive pulse (" + "is connected to the power supply positive," - "is connected to the power supply negative) makes the contact closed, negative pulse (" +" is connected to the power supply negative, "-" is connected to the power supply positive) makes the contact disconnected.After the coil is de-excited, the contact state of the contactor is maintained by the permanent magnetic steel in the product.
