Motor switching and panel fit
The Siemens 3RT2017-1AK61-Z W97 is a size S00 power contactor rated for AC-3e and AC-3 duty at 12 A, switching 5.5 kW at 400 V. That AC-3e rating means it's certified for switching three-phase squirrel-cage motors under full-load conditions — the standard for conveyor, pump, and fan starts in a control panel. The 110 V AC 50 Hz / 120 V 60 Hz coil lets it drop into North American or 50 Hz line-voltage control circuits without a control transformer. The 3-pole block carries one normally-open auxiliary contact built in, enough for a basic seal-in or status feedback to a PLC input. Screw terminals on both power and control sides keep wiring straightforward for panel builders who prefer traditional terminations over spring-cage.
RoHS compliance is confirmed since October 2009, and REACH Article 33 information is available on request. No export restrictions apply (AL: N / ECCN: N), so cross-border sourcing is straightforward.
Integration notes
Size S00 is the smallest frame in the SIRIUS 3RT2 series, measuring 61.5 x 50 x 77.5 mm. The 1 NO auxiliary is sufficient for a single feedback signal; if you need more, an auxiliary contact block can be added to the front or side.
