Scope of application
The CDZ7 series contactor relay is suitable for use in AC 50Hz/60Hz, rated operating voltage up to 660V control circuits, as a signal intermediate amplification isolation or transmission to relevant control components.

meet the standard
National standard: GB 14048.5
International standard: IEC 60947-5-1

Normal working conditions and installation conditions
1. The upper limit of the surrounding air temperature shall not exceed+40 ℃, and the lower limit shall not be lower than -5 ℃;
2. Altitude not exceeding 2000m;
3. The relative humidity of the air does not exceed 50% at+40 ℃, and can have higher relative humidity at lower temperatures. The monthly average maximum relative humidity can reach 90% when the average lowest temperature in the wettest month is+20 ℃; And allow for occasional condensation on the surface of the product due to temperature changes;
4. Atmospheric conditions: There should be no medium that poses an explosion hazard, and there should be no harmful gases or conductive dust that corrode metals or damage insulation;
5. Installation position: The inclination of the installation face towards the vertical surface shall not exceed ± 5 °;
6. Shock and vibration: The product should be installed and used in a place without significant shaking, shock, and vibration.

Technical parameters of CDZ7 series contactor relay
1. The main technical parameters of the relay are shown in the table;  
2. The working voltage of the relay is AC 36V, 110V, 127V, 220V, 380V, 660V;
3. Action characteristics: Pull in voltage: 85%~110% Us, release voltage: 20%~75% Us.



Structure to be tested
The contact adopts a forced friction structure with self-cleaning function.
The product can be equipped with auxiliary contact groups and air delay heads to expand its use. At the same time, it can be installed using 35mm standard card rails or screws.
This product is an ideal replacement for the JZ7 series intermediate relay of the old product.
