The Siemens 3VU9132-0AB18-0RE0 is an undervoltage release accessory designed for the 3VU13 and 3VU16 switch families.
Mounts directly onto the 3VU13 or 3VU16 switch body — no separate DIN-rail footprint. The release shares the switch's enclosure, so panel layout stays unchanged when adding undervoltage protection to an existing motor starter or disconnect.
