The key difference is the release: the 3VA1110 uses an electronic release (ETU) versus the thermal-magnetic TM240 on the 3VA1180. For a panel originally specified around the 3VA1110, the 3VA1180 will not drop in without rewiring if the release type or auxiliary configuration differs — verify the release curve and aux switch count before swapping."},{"question":"What compliance documentation does Siemens provide for this MCCB?","answer":"Siemens SENTRON 3VA series MCCBs carry UL, CSA, and IEC certifications as standard.
