VD4 circuit-breaker for UniGear switchgear
and PowerCube.
VD4 circuit-breaker for ZS8.4 switchgear
(VD4/ZS8 version with rotary charging).
To prevent the cabling wires outside the circuit-breaker (carried out
by the customer) from accidentally coming into contact with moving
parts and therefore undergoing damage to the insulation, it is
recommended to fix the wires as shown in fig. 10a.
Before removing the operating mechanism cover to
access the terminal box, check that the circuit-breaker is
open and the closing spring discharged.
7.8.2. Withdrawable circuit-breakers
The auxiliary circuits of withdrawable circuit-breakers are fully cabled
in the factory as far as the connector (fig. 11).
For the external connections, refer to the electric wiring diagram of the
switchgear.
