Delivery state with trans-
The vacuum circuit-breaker module can only be fitted into switchbays or switch
cabinets whose coding allows for such fitting.
The coding must not be modified.
The transport bracket locks the withdrawable part into place during transport and
must be removed as follows:
Removal of the M10 nut with washer.
Carefully pull the transport bracket forwards, lift slightly and over closing sole-
noid Y8 (optional).
Remove film and now loose nut underneath. It serves as height adjustment and
must be reused for further transport securing, as does the film.
The mechanical coding of the circuit-breaker and the cir-
cuit-breaker room prevents that similar withdrawable
sections with lower rated operating currents are fitted
into switchbays with larger rated operating currents.
For example, a circuit-breaker for 2500 A rated operat-
ing current can replace a 1250 A circuit-breaker, if the
voltage and opening values are equal or larger than
those of the 1250 A switchbay.
However, the 1250 A circuit-breaker cannot replace the
2500 A circuit-breaker.
