· Model and meaning

· normal operating conditions and installation conditions

1. The ambient air temperature does not exceed + 40 ℃, and its average temperature within 24h not exceed +35 degrees Celsius. The lower limit temperature not lower than -5 ℃.
2. the installation site altitude does not exceed 2000m.
3. The level of contamination of the surrounding atmosphere: 3.
4. humidity maximum temperature of +40 degrees Celsius, relative humidity of air no more than 50%, at a lower temperature allows a higher relative humidity, such as + 20 ℃ up to 90%.
5. No sleet attack and shock and vibration and clear the place rocking.
6. The switch should be mounted vertically.

· The main parameters and technical performance

· Structural features

switch thermosetting plastic fully enclosed structure, to ensure safe and reliable. Each group has two sets of double-break contact system, two sets of contacts connected in series to improve the switching of the current segment capacity to ensure reliable switching power supply isolation, manual rotary operating mechanism with spring energy storage, thus moving contact fast motion has nothing to do with the operating speed.
