The Siemens SENTRON 3VA1163-1AA46-0AA0 is a 4-pole switch disconnector in the 3VA1 IEC frame 160 platform, rated for 63 A continuous current without overload or short-circuit protection. It is designed as a pure disconnecting means — a load-break switch — not a circuit breaker.
Mechanical service life is 15 000 switching cycles typical, which suits infrequent manual or motor-driven isolation rather than daily process switching. Mount inside a panel with a door; this is not a standalone outdoor disconnect.
Deployment context
Front terminals accept clamp connections for main circuit wiring. The unit has no auxiliary contacts, undervoltage release, or communication function — it is a basic disconnect, intended for manual or motor-driven isolation where no remote signaling or trip capability is needed.
