The Siemens 3VA1163-6EF32-0AC0 is a SENTRON 3VA1 molded case circuit breaker (MCCB) rated for line protection, carrying 63 A continuously at 40 °C with a thermal-magnetic TM240 overcurrent release.
Interrupting rating drops with system voltage: 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 500 V or 690 V. That 17 kA floor at 690 V is the number to check if your panel feeds a 690 V drive bus — it still handles most industrial fault levels, but verify against the transformer impedance and available fault current.
Mounting and auxiliary contacts
Three-pole design, 76.2 mm wide (3 in) — fits standard 3-pole MCCB panel cutouts. Depth is 70 mm, height 130 mm.
