It is a pure disconnect — no overload or short-circuit protection — so it serves as a manual load-break switch or isolation point in a distribution panel, not as a circuit breaker. The built-in shunt trip (STL) release, rated 12–30 V DC / 24 V AC, lets a remote signal or safety circuit open the switch under load, which is useful for emergency-stop chains or controlled shutdown sequences. The 63 A continuous rating at 690 V AC covers most 400 V three-phase motor and distribution loads up to roughly 44 kW, but the part carries no trip curve — it will not clear an overload or fault. That makes it a line-side disconnect or maintenance isolator, not a branch-circuit protector. The 500 V DC rating is useful for DC bus or battery-string isolation, but verify the DC switching capacity for your specific load type; the evidence does not list a DC breaking capacity figure. The front terminals accept busbar connection (not lug or box terminals), so the panel layout must use a busbar system rather than individual cable lugs. The 70 mm depth, 76.2 mm width, and 130 mm height match the standard 3VA1 frame-160 footprint, meaning it occupies the same DIN-rail space as a 3-pole MCCB of the same frame size. ## Panel integration Front terminals accept busbar connection, so plan the busbar routing before wiring.","metaTitle":"Siemens 3VA1163-1AA32-0HA0 SENTRON Switch Disconnector, 63 A","metaDescription":"Siemens 3VA1163-1AA32-0HA0 SENTRON switch disconnector, 3-pole, 63 A continuous rating, 690 V AC / 500 V DC.
