The Siemens 3RT2016-1BB42-Z W96 is a SIRIUS 3RT power contactor rated for AC-3e/AC-3 motor switching at 9 A, handling 4 kW at 400 V. The 24 V DC coil pulls in cleanly on a standard control supply, and the single NC auxiliary contact gives you a feedback path for the PLC or a safety circuit without adding a side-mount block. Screw terminals on a size S00 frame — compact enough for a crowded DIN-rail panel, and the multi-unit packaging (72 per pack) suits a production run or a bulk MRO replenishment.
Panel integration
Size S00 snaps onto DIN rail — standard 35 mm profile. The 24 V DC coil means no AC coil hum and no separate rectifier needed; just watch polarity on the coil terminals if your panel uses a shared DC bus with free-wheeling diodes on adjacent inductive loads.
