The integrated shunt trip (STL) accepts 12-30V DC or 24V AC 50/60 Hz for remote tripping, which is the main interface for emergency-off or supervisory control circuits. Rated continuous current Iu is 100 A — this is the thermal current the main contacts carry continuously without exceeding the 70 °C maximum operating ambient. Short-time withstand current is 2 kA at both 0.5 s and 1 s — that's the fault current the closed contacts can tolerate without welding, relevant for coordination studies where upstream protection clears a fault before the disconnect opens. Power loss is 38 W maximum at rated current — a figure to check for enclosure thermal rise, especially in a sealed panel. Front protection is IP40, meaning tool-accessible terminals only; the body is not sealed against washdown. ## Panel integration Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a compact 3-pole footprint that fits standard DIN-rail or panel-mount layouts for IEC frame 160 devices. Main circuit connections are front terminals with clamp-type (screw) termination, so wiring access is from the front without side clearance. The shunt trip coil is wired separately; no auxiliary contacts are included (0 CO contacts), so if status feedback is needed, an external auxiliary switch block must be added.","metaTitle":"Siemens 3VA1110-1AA36-0HA0 Switch Disconnector, 100 A, 3-Pol","metaDescription":"Siemens SENTRON 3VA1110-1AA36-0HA0 switch disconnector, 100 A rated continuous current, 3-pole, IEC frame 160.

The key difference: the 3VA1010-2ED32-0JA0 is a molded-case circuit breaker with a TM210 thermal-magnetic release (LI protection), while the 3VA1110-1AA36-0HA0 is a switch disconnector with no overcurrent protection. They share the same mechanical footprint and terminal arrangement, so panel drop-in is possible, but the protection function is fundamentally different — do not substitute a breaker where a disconnect is s"}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA1110-1AA36-0HA0","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/3VA1110-1AA36-0HA0 when reusing this data.
