SIEMENS 3RT20181AK62 IEC Contactor
This SIEMENS 3RT20181AK62 is an IEC magnetic contactor designed for switching three-phase loads up to 16 A inductive or 22 A resistive. It operates on a 110-120V AC coil and includes one normally closed auxiliary contact for control circuit signalling. The unit belongs to the SIRIUS 3RT20 series in frame size S00.
Suited for standard motor-starting
Electrical panels requiring a compact non-reversing contactor with a 3.08 in height and 1.97 in width will fit this model. Installations that need reversing operation, a different coil voltage, additional auxiliary contacts or a built-in enclosure rating should select an alternative device.
Coil voltage 110-120V AC determines compatibility
The contactor will only energise reliably when the control supply matches this AC voltage range. Verify the panel control voltage before purchase; a mismatch will prevent the contactor from operating.

Questions about this item
At what inductive current does this 16 A contactor reach its thermal limit during continuous operation?
The contactor is rated for 16 A full-load inductive current; sustained operation above that level will exceed its thermal limit.
How much heat does the coil dissipate when energised at 110 V AC all day?
The coil is designed for continuous 110/120 V AC duty; normal heat rise is within IEC limits for the S00 frame.
What control-voltage source must I already have to operate the 110/120 V AC coil?
You need a 110 V to 120 V AC supply capable of powering the contactor coil.
