4.7 Conversion kit for withdrawable circuit breakers and rating coding of the guide frame
3WA1 air circuit breaker
302 Equipment Manual, 02/2023, 92310000002-06
Rated-current coding
Rated-current coding ensures that only those circuit breakers whose guide frames are
suitable for the circuit breakers can be inserted into the guide frame.
Every design version has a separate coding.
When converting a fixed-mounted circuit breaker into a withdrawable circuit breaker, the
coding for rated current and breaking capacity must be retrofit by the customer on both
the circuit breaker and the guide frame.
Note
When withdrawable circuit brea
kers are ordered, withdrawable circuit breakers and
guide frames are already equipped with coding for rated current and breaking capacity at
the factory.
You will find more information in the operating instructions available on the internet
