RDA1 series Push button CE

In the electric automatic control circuit, it is used to manually send control signals to control contactors, relays, electromagnetic starters, etc. Generally, the main circuit is not directly operated, but can also be used in the interconnection circuit. In actual use, in order to prevent misoperation, buttons are usually marked or painted with different colors, including red, yellow, blue, white, black, green, etc. Generally, red indicates operation under “stop” or “dangerous” conditions; Green means “ON” or “ON”. The emergency stop button must be red mushroom head button.

Main Technical data

Model No.

Normal working condition and installation condition

3.1 Altitude: lower than 2000m.
3.2 Ambient temperature: no higher than +40°C,and no lower than -5°C, and day average temperature shall no more than +35°C.
3.3 Humidity: Relative humidity shall not excced 50% at the Max temperature 40°C, and higher humidity could be accepted at lower temperature. The condensation must be taken care which is caused by temperature change.
