The coil pulls 3.2 W DC and holds at the same power, which means the supply transformer or DC bus needs to budget that draw continuously while the contactor is energized.
The front is IP20-rated, so it's protected against accidental finger contact but not against washdown — keep it inside the cabinet.
The 6 NO contacts are rated for AC and DC switching across common control voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. That covers most 24 VDC PLC outputs and 230 VAC pilot-duty circuits in a single device. The contacts are instantaneous (no make-before-break or delayed action), so they switch cleanly with the coil state. The surge voltage withstand is 6 kV, adequate for industrial environments with moderate transient exposure.
This part is a standard catalog item from the Siemens SIRIUS line. It carries a substance prohibition date of 01.07.2006, aligning with RoHS compliance for lead and other restricted substances. No UL or CSA mark is listed in the evidence, but the IEC ratings cover most global installations outside North America — verify local code acceptance if the panel requires a UL-listed auxiliary contactor.
