Closing
Description

Description and operation
Pole operation
(Interrupting principle)
When an electrical or manual closing order is given, the energy accumulated
in the closing spring (17) - situated inside the operating device - is released.
This energy is transmitted directly to the pole operating shaft (18), to ensure
closing by way of the transfer mechanism inside the housing (11).
The release of the energy stored up in the closing spring (17) causes displace-
ment of the moving parts - and so the closing of the interrupting chambers
- and also reloads the opening spring (9).
