The Siemens 3RT1016-1AF01-ZI41W96 is a 3-pole contactor from the SIRIUS 3RT1 series, size S00, with screw terminals and a 110 V AC 50/60 Hz coil. The 1 NO auxiliary contact is built in for status feedback or interlocking. The coil pulls in reliably at 110 V AC, 50/60 Hz, which is a standard control voltage across European and many Asian panels. The size S00 footprint keeps the DIN-rail space tight — roughly 45 mm wide — so it fits in a crowded enclosure without forcing a bigger cabinet.
What the AC-3 rating means for your motor load
The 4 kW at 400 V rating is the maximum motor power it can handle in that duty cycle. If your motor nameplate exceeds 4 kW, step up to the next S00 frame size or move to a larger S0 contactor.
Multi-unit packaging — what to expect
This variant ships in a multi-unit pack of 20 pieces. That's a single carton with twenty identical contactors, intended for OEM builds or panel shops that burn through a batch at once. Strip length around 8–9 mm for a proper connection.
