Power dissipation maxes at 38 W, which should be factored into enclosure thermal calculations for a multi-breaker lineup. ## What this part is for — and what it isn't This is a switch disconnector, not a molded case circuit breaker. It provides visible isolation and load-break capability at 160 A but has no overcurrent or short-circuit protection — no trip curve, no overload adjustment. The shunt trip (STL) is the only integrated release; there is no undervoltage release or communication module. The closest functional peer, the 3VA1110-5EE32-0JA0, is a full MCCB with a TM220 thermal-magnetic release and 100 A frame rating. That part offers LI protection (long-time and instantaneous) and a much higher interrupting capacity — 187 kA at 240 V — but lacks the switch-disconnector's pure isolation role. The 3VA1116-1AA32-0HC0 is the right choice when the upstream breaker handles fault clearing and you need a local disconnect with remote trip capability. Dimensions: 76.2 mm wide (3-inch footprint), 130 mm tall, 70 mm deep. Front terminals accept busbar connection for the main circuit — common in panelboard and switchboard builds where a common bus feeds multiple disconnects. The shunt trip coil draws from a separate 12–30 V DC or 24 V AC supply — not from the main bus. Wire the control voltage through a remote E-stop or PLC output for load shedding. The two HQ auxiliary contacts (CO form) provide independent NO/NC feedback for status indication or interlocking. Suitable for indoor panel environments within those limits.","metaTitle":"Siemens 3VA1116-1AA32-0HC0 SENTRON Switch Disconnector, 160","metaDescription":"Siemens SENTRON 3VA1116-1AA32-0HC0 switch disconnector, 160 A rated, 3-pole, with shunt trip STL 12-30V DC and 2 HQ aux switches.

The 3VA1110-5EE32-0JA0 is a full MCCB with a TM220 thermal-magnetic release, 100 A rating, and LI protection — it interrupts faults up to 187 kA at 240 V.

However, the 3VA1116-1AA32-0HC0 uses busbar connection on the main circuit, while the 3VA1110-5EE32-0JA0 uses lug terminals — verify busbar interface compatibility before swapping."},{"question":"What are the key specs of 3VA1116-1AA32-0HC0?","answer":"Rated continuous current 160 A, 3-pole, rated insulation voltage 800 V, max operational voltage 690 V AC / 500 V DC, shunt trip STL 12-30V DC / 24 V AC, 2 HQ auxiliary contacts, IP40 front, 15 000 mechanical cycles, 38 W max power loss."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1116-1AA32-0HC0","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/3VA1116-1AA32-0HC0 when reusing this data.
