Automatic switch for industrial and mining electric locomotives

The series of automatic switches for industrial and mining electric locomotives are suitable for traction electric locomotives used in general metal mines or coal mines without explosion hazards. They are used as the main power switch and over-current protection of the main circuit of the electric locomotive.

This series of automatic switches are suitable for the following working environments

●The altitude does not exceed

●The ambient temperature is ℃~+℃
< br/>●The relative humidity of the surrounding air does not exceed There are no harmful gases and conductive dust that are enough to corrode metal and destroy insulation

●The inclination relative to the normal position is not greater than

●The impact acceleration relative to the longitudinal direction of the locomotive is not greater than / , the locomotive has a sinusoidal vibration with a frequency of

~ in the vertical, longitudinal and transverse directions, and its amplitude is
