The Siemens 3RT2016-2AP02-1AA0 is a size S00 power contactor from the SIRIUS 3RT2 family, rated for AC-3e and AC-3 duty at 9 A, switching motor loads up to 4 kW on a 400 V three-phase line. The AC-3e rating means it's tested for the higher electrical endurance of modern energy-efficient motors — so if you're replacing a contactor on a line with IE3 or IE4 motors, this rating matches the switching stress those motors generate. The 230 V AC coil operates on 50/60 Hz, which is the standard control voltage across European and much of Asian panel infrastructure. The 1 NC auxiliary contact is built in, so you get a feedback or interlock signal without adding a separate auxiliary block. The S00 frame size is the smallest in the 3RT2 family, so it fits in tight DIN-rail enclosures where every millimeter of width matters.
Compliance and regulatory documentation
RoHS compliance is confirmed since October 2009, and REACH Article 33 duty-to-inform data is available through the manufacturer's declaration system. Export control is classified as AL: N / ECCN: N, so no special licensing is needed for cross-border shipment within standard industrial automation channels.
