SIEMENS 3RT20271AN20 IEC Magnetic Contactor
The SIEMENS 3RT20271AN20 is a non-reversing, three-phase magnetic contactor with a 208V AC coil voltage. It belongs to the SIRIUS 3RT20 series and is designed for vertical mounting on DIN Rail or Surface. The unit features a 1NO/1NC auxiliary contact configuration with two auxiliary contacts and carries an IP20 rating with no enclosure.
Industrial motor control panels needing 32
This contactor suits applications requiring up to 32 A full-load inductive current and 50 A resistive current at 208V AC coil supply. It operates between -13 Degrees F and 140 Degrees F with mechanical durability tested to ten million cycles. Buyers needing an enclosed device, a different coil voltage, or higher inductive current ratings should look at alternative contactors.
32 A inductive / 50 A resistive full-load current
The contactor delivers 32 A full-load amps inductive and 50 A full-load amps resistive across three poles. Horsepower ratings range from 2 hp at single-phase 120V AC up to 25 hp at three-phase 600V AC. Watts loss is current dependent at 2.3W and current independent at 10.5W. Overall dimensions are depth 4.3 in, height 3.6 in, width 2.2 in with screw terminal connections.

Questions about this item
Does the 3RT20271AN20 fit a standard DIN rail or does it need a panel cut-out?
It is designed for vertical mounting on either DIN rail or directly on a flat surface using screws.
What wiring step is most often missed when installing the 208 V AC coil and auxiliary contacts?
Use screw terminals for both the main circuit and the 1NO/1NC auxiliary contacts, and verify the coil is rated for 208 V AC before energising.
How long before the main contacts on this 32 A inductive contactor typically need replacement?
Mechanical durability is tested to ten million cycles; electrical life depends on load duty cycle and operating temperature between -13 °F and 140 °F.
