It is configured without overload or short-circuit protection — this is a disconnect-only device, not a circuit breaker. The integrated shunt trip (STL) release operates on 110-127 V DC or AC 50/60 Hz, per the product designation. The 100 A rated continuous current (Iu) sets the maximum load it can carry continuously without exceeding temperature limits. Rated insulation voltage Ui is 800 V, with max operational voltage 690 V AC 50/60 Hz and 500 V DC. That covers standard 400/480 VAC three-phase systems and many DC bus applications up to 500 V. The 2 kA limited short-time withstand (1 s and 0.5 s) tells you this disconnector is rated to hold closed under fault current up to 2 kA for those durations. It is not a breaker — it does not interrupt faults. Upstream protection must clear any fault before the disconnector's short-time rating is exceeded. ## Deployment context This is a panel-mounted switch disconnector for isolating a load circuit. The busbar connection on the front terminals means it integrates into a busbar distribution system — typical for main incomers or large sub-feed disconnects in industrial switchboards. The 76.2 mm width (roughly 4.5 module spaces) and 70 mm depth fit standard SENTRON 3VA1 panel cutouts.","metaTitle":"Siemens 3VA1110-1AA32-0JA0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA32-0JA0 SENTRON switch disconnector, 100 A rated continuous current, 3-pole, MCCB design, shunt trip STL 110-127 V DC/AC.

The critical difference is function: 3VA1010-2ED32-0JA0 is a molded case circuit breaker with line protection (overload and short-circuit), while 3VA1110-1AA32-0JA0 is a switch disconnector with no overcurrent protection. If the panel design relies on the breaker's protective function, a direct swap is not electrically equivalent — upstream protection must be verified."},{"question":"What are the key ratings for 3VA1110-1AA32-0JA0?","answer":"Rated continuous current Iu = 100 A, 3-pole, rated insulation voltage Ui = 800 V, max operational voltage 690 V AC 50/60 Hz and 500 V DC, short-time withstand 2 kA for 1 s and 0.5 s, max power loss 38 W, IP40 front protection, operating temperature range -25 °C to +70 °C."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1110-1AA32-0JA0","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/3VA1110-1AA32-0JA0 when reusing this data.
