1、 Purpose

CZY1-c (for electromagnetic mechanism  permanent magnet mechanism) instantaneous working DC contactor (patented technology) is applicable to the electromagnetic operating mechanism with rated voltage up to 220 V DC for remote instantaneous connection  breaking of high-voltage circuit breaker. Because the coil is cut off immediately after the circuit breaker acts, the coil is designed as instantaneous working system.

3、 Installation  service conditions

1. The altitude of the installation site should  exceed 2000m (special instructions should be given when ordering in high altitude areas);

2. The ambient air temperature is - 25 ℃ ~ + 40 ℃;

3. The inclination angle between the installation surface  the vertical plane is less than + 22.5 ° (see Figure). When the site vibration is large, it is recommended to install in the vertical direction of vibration to prevent the vibration  sucking in;

4. It is installed in the environment that can prevent rain, snow, wind  sand.
