1.      Main Application

Being used as anxiliary device for High-voltage circuit-breaker, high-voltage isolator, low-voltage isolator, low-voltage automatic air switch and low-voltage knife switch, series F switch controls the process of making and breaking signal.

 

2.      Working Conditions

1.      Ambient Temperature (-40℃≤ t ≤40℃)

2.      Height above Sea Level (h≤3000m)

3.      t=+25℃, relative air humidity ≤ 90%

4.      Situation of no sharp pounding, no explosion risk, no inductive dust, no air destroying insulators or corroding metal and so on.

 

3.      Structure

1.      According to different requirements, the turning angle of series F1 could be 60°~90°~120°.

2.      Series F1 is devided into straight type and horizontal type according to the assembling method. It’s devided into horizontal structure and straight delay contact according to the way of construction.
