It is designed as a manual disconnect, not a breaker, so it sits downstream of an upstream protective device. Rated insulation voltage is 800 V, with a maximum operational voltage of 690 V AC 50/60 Hz and 500 V DC. The part is rated for a short-time withstand current of 2 kA at both 0.5 s and 1 s — this is the fault current it can carry momentarily without damage, not a breaking capacity. It is not a circuit breaker; it is a load-break switch intended for isolation and emergency switching. Dimensions are 70 mm deep, 76.2 mm wide, and 130 mm tall — a compact footprint that matches other 3VA1 frame devices, so it can be swapped into an existing panel layout without re-drilling. Front terminal connections for the main circuit accept lug or clamp-type conductors, and the two auxiliary switches are wired via the front-accessible terminals. IP40 on the front face keeps out tools and fingers; the rest of the enclosure relies on the panel environment. The 63 A rated continuous current (Iu) sets the maximum load this switch can carry continuously without exceeding its thermal limits. For motor loads, size it to the full-load current of the motor plus a margin; for resistive loads, it can run at 63 A continuous. The shunt trip release allows remote tripping from an E-stop or safety PLC — the 220-250 V DC / 208-277 V AC coil voltage means it needs a control supply in that range. The two HQ auxiliary contacts provide a clean signal for status monitoring; they are rated for the same control voltage as the shunt trip. The latching endurance of 15 000 operations is the mechanical life; electrical life will be lower depending on the switched load.","metaTitle":"Siemens 3VA1163-1AA36-0KC0 Switch Disconnector, 63 A, Shunt","metaDescription":"Siemens SENTRON 3VA1163-1AA36-0KC0 switch disconnector, 63 A rated continuous current, shunt trip release 220-250 V DC / 208-277 V AC.
