45 mm wide SIRIUS S00 — panel-fit and what it contains
The 3RA2110-0EA15-1BB4: This is a factory-assembled SIRIUS S00 direct (on-line) starter — the contactor (3RT2015-1BB41) and the link module (3RA1921-1DA00) ship as one unit, saving you the assembly time and the risk of mismatched components on the DIN rail. The 90 kW rating at 400 V (AC-3) tells you this handles a substantial motor load — think pumps, compressors, or conveyors in the 90 kW class — but note the AC-3 current rating at 400 V is 0.4 A, which is the contactor's rated operational current for that duty.
Class 10 protection — thermal bimetal and magnetic short-circuit trip
Short-circuit protection uses a magnetic trip (instantaneous), sized for the S00 feeder — coordination with upstream protection is straightforward for a panel builder. Operating temperature range is -20 to +60 °C, with storage from -50 to +80 °C — this starter can sit in an unheated warehouse or a warm panel room without issue.
