IEC Magnetic Contactor 24V AC
The SIEMENS 3RT20161AB02 is a three-pole IEC magnetic contactor with a 24V AC coil and one normally closed auxiliary contact. It is designed for switching inductive loads up to 9 A and resistive loads up to 22 A in industrial control circuits. The non-reversing SIRIUS 3RT20 series unit suits panel builders and maintenance engineers who need reliable motor or heater control.
Screw terminal limits and DIN rail mounting
Screw terminals accept solid or stranded conductors tightened by hand tool, setting a practical limit on wire gauge and installation speed. The contactor mounts on a standard DIN rail or directly on a panel surface, so enclosure depth must accommodate the 3.08 in overall height and 1.97 in width. Coil operation at 24V AC requires a compatible control transformer or power supply.
Compact frame with no enclosure rating
Frame size S00 keeps the footprint small for crowded panels, while the absence of a NEMA enclosure rating means the device must be installed inside a suitable cabinet. One normally closed auxiliary contact provides status feedback or interlocking without extra accessories. The 20161 model number identifies this specific SIRIUS 3RT20 variant for ordering and documentation.

Questions about this item
Should I choose the 9 A inductive or the 22 A resistive rating for my load?
Use the 9 A inductive rating for motor loads and the 22 A resistive rating for heating or lighting circuits.
What does the 24 V AC coil voltage mean when the contactor is installed in a panel?
The coil requires a 24 V AC control supply; it will not operate on DC or higher AC voltages.
How does the IEC frame size S00 affect mounting and wiring?
Frame size S00 fits a standard DIN rail or surface mount and uses screw terminals for power and control connections.
