What it is and what it does
The Siemens 3RV2411-1EA10-Z W97 is a SIRIUS 3RV2 motor starter protector in frame size S00, specifically configured for transformer protection. The A-release is set at 2.8...4 A, and the short-circuit release trips at 82 A. It uses screw terminals and standard switching capacity.
Where it fits
Frame S00 is the compact footprint in the SIRIUS family, designed for DIN-rail mounting inside control panels. The screw terminals accept standard panel wiring, and the multi-unit packaging (12 pieces per pack) suits OEM builds or panel shops that batch-assemble motor control centers.
Ratings and what they mean
The A-release range of 2.8...4 A sets the overload protection band for the transformer primary — this is the rating that determines fit for a given transformer kVA and inrush characteristic. The 82 A short-circuit release handles fault clearing without nuisance tripping on magnetizing inrush.
Compliance and documentation
RoHS compliant since October 2009, and REACH candidate-list information is available from Siemens. Export control is AL: N / ECCN: N, meaning no special license required for most destinations.
