SIEMENS 3RT20281AN20 Contactor
The SIEMENS 3RT20281AN20 is a three-pole IEC magnetic contactor from the SIRIUS 3RT20 series. It operates on a 208 V AC coil and provides one normally open and one normally closed auxiliary contact. The unit is rated for 38 A inductive and 50 A resistive full-load current.
Industrial control panels and motor starters
This contactor suits panels that need a compact IEC device with screw terminals for DIN rail or surface mounting. It is not for applications that require a reversing contactor, a built-in enclosure or a different coil voltage than the specified 208 V AC.
208 V AC coil voltage
The coil voltage of 208 V AC is the single specification that determines whether this contactor matches the control circuit. Verify the supply voltage before ordering, as the device will not operate correctly on other voltages.

Questions about this item
Should I choose the 208 V AC coil version or the 220 V AC coil version for my control circuit?
The contactor operates on a 208 V AC coil; a 220 V AC coil is a separate variant. Select the version that matches your control voltage exactly.
What does the 38 A inductive full-load current mean for my motor circuit?
It rates the contactor for switching inductive loads such as motors up to 38 A. Resistive loads can go to 50 A.
How does the screw-terminal interface limit wire size and installation?
Screw terminals accept standard stranded or solid conductors for the S0 frame. Tighten to the specified torque for reliable contact.
