De-rate the continuous current as ambient climbs: 62 A at 55 °C, 60 A at 65 °C, 58 A at 70 °C. That's a standard 3-pole MCCB envelope — drops into most panel-mounted or DIN-rail adapter bases without re-drilling the backplate. ## Peer fit — 3VA1110-5ED36-0AC0 comparison If you're cross-referencing against the 3VA1110-5ED36-0AC0: that's a 100 A frame with a different thermal-magnetic curve. The 3VA1163-5EF36-0AB0 is a 63 A frame — same SENTRON platform, same 3-pole layout, same 70 mm depth, so it will physically occupy the same mounting footprint. But the trip unit and continuous rating differ; swapping them without verifying the load's FLA and the coordination study is a mistake. The 3VA1110 frame goes to 100 A; this one tops at 63 A. Use the 3VA1163 where the BOM calls for 63 A line protection and you need the higher interrupting capacity at 240 V.","metaTitle":"Siemens 3VA1163-5EF36-0AB0 SENTRON MCCB, 63A, 187kA at 240V","metaDescription":"Siemens 3VA1163-5EF36-0AB0 SENTRON molded case circuit breaker, 3-pole, 63A continuous, 187kA interrupting at 240V.
