The CZY22 series DC contactor is a newly developed product by Dongmu Company, with a rated current ranging from 40A to 80A and two normally open and two normally closed main contacts. CZY22 innovatively uses permanent magnet arc extinguishing technology, effectively solving the key problems of difficult critical breaking current and excessive wear of contacts in traditional contactors.

1、 Purpose:
The CZY22 series DC contactor is suitable for frequent connection and disconnection of DC circuits over long distances. Its main control object is DC motors, and it is widely used in fire control equipment; It can replace dual power supply in the high-voltage switch control cabinet.


3、 Installation and usage conditions
1. Altitude not exceeding 2000m (special instructions should 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 vertical surface is less than+22.5 ° (as shown in the figure). When there is a large on-site vibration, it is recommended to install in the vertical vibration direction to prevent the mechanism from vibrating and accidentally engaging;
4. Installed in an environment that is resistant to rain, snow, wind, and sand;
5. Install with screws or 75mm U-shaped guide rails.
