IEC Magnetic Contactor 24V AC 3P 1NO
The SIEMENS 3RT20161AB01 is a non-reversing IEC magnetic contactor designed for controlling three-phase motor loads and other inductive circuits. It operates on a 24V AC coil voltage and provides one normally open auxiliary contact for status signalling or interlocking. The unit belongs to the SIRIUS 3RT20 series with frame size S00. It is suited for industrial control panels and machinery automation.
Check coil voltage and mounting before ordering
Verify that your control circuit supplies 24V AC to match the coil rating. Confirm the available panel space accommodates the overall height of 1.95 in and width of 2.4 in. Ensure the DIN rail or surface mounting style fits your enclosure layout. The contactor uses screw terminals for power and control connections. The inductive full load current is rated at 9 A and resistive at 22 A.
Suits panels needing a compact 3-pole starter
This contactor suits builders assembling motor starters or lighting contactors where a single 1NO auxiliary is sufficient and non-reversing operation is required. It is not for applications needing reversing capability or additional auxiliary contacts beyond the one provided. Buyers who need a different coil voltage or higher current ratings should look at other models. The lack of a NEMA enclosure rating means a separate enclosure is necessary for environmental protection.

Questions about this item
Does the SIEMENS 3RT20161AB01 contactor come with auxiliary contacts or must they be ordered separately?
The contactor includes one normally open auxiliary contact as part of the 1NO configuration.
How do I choose between the 9 A inductive and 22 A resistive ratings for my load?
Use the 9 A rating for motor or transformer loads and the 22 A rating for heating or lighting loads.
What does the 24 V AC coil voltage mean for my control circuit wiring?
The coil requires a 24 V AC control supply; ensure your control transformer or PLC output matches this voltage.
