This is a pure disconnector — it provides no overload or short-circuit protection, so it's specified where the upstream breaker or fuse already handles fault interruption and you need a local, lockable isolation point for a motor, panel, or machine section. Rated for 690 V AC and 500 V DC. Front terminal arrangement with busbar connection keeps the footprint tight for panel layouts. The shunt trip release (STL) is factory-fitted for 220-250 V DC or 208-277 V AC — a remote trip coil that lets a safety circuit, E-stop, or PLC output open the disconnector without someone pulling the handle. Two auxiliary switches plus a dedicated trip alarm switch (HQ) give status feedback: one set for open/closed indication, one for the trip event. The 3-pole body fits the standard 3VA1 panel cutout and DIN-rail adapter pattern — if you're swapping into an existing SENTRON 3VA1 lineup, the footprint matches the frame-160 switch disconnector and MCCB variants. Maximum power loss of 38 W at rated current — factor that into panel thermal calculations if the enclosure is sealed or densely populated.","metaTitle":"Siemens 3VA1110-1AA32-0KH0 SENTRON Switch Disconnector, 100","metaDescription":"Siemens 3VA1110-1AA32-0KH0 SENTRON switch disconnector, 100 A rated continuous current, 3-pole, IP40 front, shunt trip release.
