The 3VA1163-5EF36-0KA0 carries a 63 A TM240 release versus the 3VA1110's lower rating, so the load-side conductors and busbars must be sized for the higher continuous current — the mechanical fit is the same, but the electrical sizing is not."},{"question":"What compliance documentation does this brand provide for 3VA1163-5EF36-0KA0?","answer":"Siemens SENTRON MCCBs carry IEC 60947-2 certification as standard. RoHS and REACH declarations are published on the Siemens Industry Online Support portal under the 3VA1 series documentation.
