IEC Magnetic Contactor for Motor Control
The SIEMENS 3RT20161AK643MA0 is a three-pole IEC magnetic contactor rated for 110 to 120 V AC coil voltage. It provides 9 A inductive and 22 A resistive full-load current capacity with a 2NO/2NC auxiliary contact configuration. The unit belongs to the SIRIUS 3RT safety contactor series in frame size S00.
Verify Coil Voltage and Mounting Space
Confirm that your control circuit supplies 110 V AC or 120 V AC to match the coil rating before installation. The contactor measures 2.45 in overall height and 1.5 in overall width, so check available panel depth and DIN rail spacing. Ensure the application does not require reversing capability, as this model is non-reversing.
Screw Terminals and Four Auxiliary Contacts
Screw terminal connections accept standard ferrules or bare wire for secure power and control wiring without specialised tools. The integrated 2NO/2NC auxiliary contacts eliminate the need for separate accessory blocks for common interlock or status signalling tasks. The open design has no enclosure rating, so the installer must provide suitable cabinet protection.

Questions about this item
Does the contactor ship with any cables or DIN-rail clips, or must those be purchased separately?
The unit is supplied as the contactor only; screw-terminal wiring and DIN-rail mounting hardware are not included and must be sourced separately.
Which coil voltage version should I select for a 110 V to 120 V AC control circuit?
This model operates on 110/120 V AC coil voltage, matching control circuits in that range.
What does the 9 A inductive current rating mean for a motor load in practice?
It indicates the contactor can switch up to 9 A on inductive motor loads at the rated voltage.
