Figure 2/14: Dimensional drawing of circuit-breaker type VD4:
high-current, 24 kV, ...2500 A, ... 25 kA.
K = Cable entry
T = Handling bores, both sides
Note: Remove the lifting lugs on both sides before commissioning
A = View „A“
GA = Tested terminal zone
M = Minimum distance to DIN VDE 0101
A1 = Terminal for contact arm
A2 = Terminal for connecting bar
A3 = Terminal bar to DIN 46 433,
for 24 kV shrink sleeve fitted
= Earthing conductor terminal, use contact washer
