Rated continuous current Iu is 63 A, with no overload or short-circuit protection onboard. That makes it the right choice for a manual disconnect point where upstream protection already exists, or for safe isolation during maintenance on a 3-pole load circuit. The integrated shunt trip release (STL) operates on 220–250 V DC or 208–277 V AC, letting you trip the disconnector remotely via a control signal — useful for emergency-stop chains or remote load shedding where you need to break the circuit without walking to the panel. No undervoltage release is fitted, so the disconnector holds in regardless of control voltage loss; only a deliberate shunt-trip pulse opens it. Three-pole, 70 mm deep, 76.2 mm wide, 130 mm tall — the same compact 3VA1 frame dimensions as the equivalent breaker versions. Front terminal connection for the main circuit, clamp-type terminals. The 3VA1 frame accepts an optional motor drive, so this disconnector can be automated for remote switching without losing the manual disconnect function. No auxiliary contacts are fitted as standard; if you need status feedback, plan for an add-on auxiliary contact block. ## Voltage and endurance Mechanical endurance is 15,000 operating cycles. Power loss at rated current maxes at 38 W.","metaTitle":"Siemens 3VA1163-1AA36-0KA0 SENTRON Switch Disconnector, 63A","metaDescription":"Siemens 3VA1163-1AA36-0KA0 SENTRON switch disconnector, 3-pole, 63A rated continuous current, shunt trip STL 220-250VDC / 208-277VAC.

It will physically drop into the same panel cutout and bus connection, but it is a circuit breaker, not a switch disconnector — it adds protection and removes the pure-isolation role.

Both parts share the same 3VA1 frame dimensions (70 mm deep, 76.2 mm wide, 130 mm tall) and front-terminal connection arrangement, so the physical footprint and bus-bar positions are identical. No rewiring of the main circuit is needed for the swap, but the 3VA1163-1AA36-0KA0 is a switch disconnector without overcurrent protection, so the upstream protection must already cover the load."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1163-1AA36-0KA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA1163-1AA36-0KA0 when reusing this data.
