Your question is a bit unclear. The 3WL circuit breaker is an ACB "Air Circuit Breaker". The 3VL circuit breaker is a MCCB "Molded Case Circuit Breaker".
Please see attached page from the LV 1 T 2009 catalog. There you'll find the Icu value for the 3WL circuit breaker. You'll see that every 3WL circuit breaker, independent to the switching capacity class, fulfill the requirement or Icu = 40kA@690V.
