1、 Purpose:
Suitable for long-distance connection and disconnection of DC circuits and frequent starting, stopping, reversing, and reverse braking of DC motors.

3、 Installation and usage conditions
1. The altitude of the installation location shall not exceed 2000m (special instructions shall be provided when ordering in high-altitude areas);
2. The ambient air temperature ranges from -25 ℃ to+40 ℃;
3. The inclination angle between the installation surface and the heavy surface is less than ± 22.5 (as shown in the figure). When there is significant vibration on site, it is recommended to install in the direction of direct vibration to prevent vibration absorption;
4. The contactor used in the quick release spring mechanism should be installed strictly in the direction shown in the diagram, while considering the shock resistance of the installation screws;
5. Installed in an environment that is resistant to rain, snow, wind, and sand.
