The Siemens 3RU1900-2AB71 is an electronic remote reset module from the SIRIUS family, designed to remotely reset overload relays after a trip event without requiring panel access.
This reset module mounts onto Siemens SIRIUS overload relays in frame sizes S00, S0, S2, and S3 — the full range of standard IEC motor-protection relays. The screw-type auxiliary and control terminals accept two conductors per clamp: 0.5 to 1.5 mm² or 0.75 to 2.5 mm² solid/stranded, or finely stranded with ferrule.
It fits SIRIUS overload relay frame sizes S00, S0, S2, and S3.
The control supply voltage is 24 to 30 V AC/DC, compatible with 50 Hz and 60 Hz supplies.
