1、 Purpose

Jzy1-k fast DC relay is suitable for DC operation of various protection  automatic control lines, as an outlet relay  to increase the number  capacity of protection  control circuit contacts.

The contact breaking time of common DC operated relay is more than 30ms. Jzy1-k fast DC relay can meet the requirements of DC operation quick breaking less than 20ms,  can meet the requirements of high-voltage switch anti tripping protection line after high-voltage switch factory test.

4、 Conditions of use

1. The altitude shall  exceed 2000m;

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

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

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