7.7 Connection of 3WT8 air circuit breakers
Note
Implementation of the power supply
More information on implementing the power supply of the ATC6500 via the inputs 53, 54
and / or the inputs 26, 27 can be found in chapter Connection of the power supply (Page 83).
Note
Mechanical / electrical interlocks
The two breakers of the infeed sources are electrically interlocked in the circuit diagram
shown above. The tie breaker is not interlocked. An additional mechanical interlock can be
applied for the two breakers BRK1, BRK2.
Note
Expansion modules
For additional functions, expansion modules with inputs/outputs can be attached if necessary
(see chapter Expansion modules (Page 209)).
You can find more information on the technical specifications of the circuit breaker in the
Operating Manual of the SENTRON 3WT8 air circuit breaker
(https://support.industry.siemens.com/cs/ww/en/view/33272206).
