The Siemens 3VU9132-0AB57-0RE0 is a shunt release accessory designed for the 3VU13 and 3VU16 switch families. It operates on a 400 V AC supply at 50 Hz, providing remote tripping capability for those switches in a panel or enclosure.
Mounts as an accessory on the 3VU13 or 3VU16 switch base — typically inside a control panel or motor starter enclosure. The 400 V AC coil is wired to a control circuit; when energized, it mechanically trips the switch. Verify the coil voltage matches your control supply before installation.
