It carries no overload or short-circuit protection elements — this is a pure disconnecting switch for applications where protection is handled upstream or by separate devices. The shunt trip release (STL) operates on DC or AC voltage. Two auxiliary switches (HQ) provide status feedback via one normally-open and one normally-closed contact pair, giving two changeover contacts total. The main circuit connects via busbar connection at the front terminals. The 3VA1112-1AA32-0KC0 occupies a 76.2 mm wide, 130 mm tall, 70 mm deep footprint — standard for the 3VA1 frame. It mounts in a panel or enclosure with front-terminal busbar connections. Maximum power loss is 38 W, which matters for thermal management inside a sealed enclosure. Mechanical service life is rated 15,000 operating cycles typical. An optional motor drive can be added for remote operation. The part carries no communication function.","metaTitle":"Siemens 3VA1112-1AA32-0KC0 SENTRON Switch Disconnector, 125","metaDescription":"Siemens 3VA1112-1AA32-0KC0 SENTRON switch disconnector in MCCB design.

The switch disconnector has no overcurrent release, so the panel wiring for the main circuit is identical, but the auxiliary contact arrangement differs (this unit has 2 CO contacts; the MCCB variant has none). If the panel relies on those auxiliary contacts for status feedback, no rewiring is needed — they are already present."},{"question":"What compliance documentation does this brand provide for 3VA1112-1AA32-0KC0?","answer":"As a Siemens SENTRON product, it carries the manufacturer's standard compliance documentation including CE marking for the European market.
