SIEMENS 3RT20171AK62 3-Pole Contactor 110-120V AC 1NC
Three-pole IEC contactor rated 12 A inductive and 22 A resistive with 110–120 V AC coil and one normally-closed auxiliary contact
- IEC-rated contactor for standard industrial control
- 110-120 V AC coil matches common panel voltage
- 12 A inductive load rating handles motor duty
- 3-pole main circuit plus 1 NC auxiliary contact
- Compact S00 frame mounts on DIN rail or surface
IEC Magnetic Contactor for Motor Control
The SIEMENS 3RT20171AK62 is a three-pole IEC magnetic contactor rated for 110-120V AC coil voltage. It handles 12 A inductive and 22 A resistive full-load current with a single normally closed auxiliary contact. This new component suits industrial control panels and machinery starters.
DIN Rail Mounting with Screw Terminals
The unit mounts on DIN rail or directly on a surface within a compact S00 frame measuring 2.6 in height and 2.5 in width. Screw terminals provide secure power and control wiring without special tools. The non-reversing design requires a separate contactor pair for motor direction changes.
1NC Auxiliary Contact for Status Feedback
The built-in 1NC auxiliary contact opens when the main poles close, giving a simple signal for interlocking or indication circuits. No enclosure is included, so the contactor must be installed inside a suitable cabinet. The SIRIUS 3RT20 series construction supports standard IEC control schemes.

Questions about this item
Will the 12 A inductive load rating hold continuously without overheating?
The contactor is rated for 12 A inductive and 22 A resistive full-load current, so sustained 12 A inductive operation stays within its thermal design.
How much heat and noise does the 110-120 V AC coil produce during all-day operation?
The AC coil draws only a few watts when sealed, so heat rise is modest and the contactor runs silently with no fan or moving parts after pull-in.
Does the screw-terminal block accept the wire gauges I already have in the panel?
The S00 frame uses standard screw terminals that accept solid or stranded conductors up to 4 mm², matching typical panel wiring practice.
