Description and operation
Pole operation
(Interrupting principle)
When an electrical or manual opening order is given, the energy accumulated
in the opening spring (9) is released.
The insulating tie- rod (10), directly activated by the opening spring (9), trans-
mits the movement to the transfer mechanism (11) inside the housing which
causes the contacts to separate simultaneously in both chambers.
After the separation of main contacts (3) and beginning of gas compression
(G), the resistor insertion device (5) return is time- delayed by pneumatic
effect (depression of the "X" volume).
