Coding
Delivery state with trans-
port bracket
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.
Note
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 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.
