SIEMENS 3RT23251AK60 contactor 1NC/1NO 110-120V AC 4P
Four-pole IEC contactor rated 16 A inductive and 35 A resistive with 110-120 V AC coil, 1NO/1NC auxiliary contacts and DIN-rail or surface mounting
- 4-pole contactor handles 35 A resistive loads
- 16 A inductive rating suits motor starting duties
- 110–120 V AC coil fits standard control voltages
- DIN-rail or surface mount simplifies panel installation
- Screw terminals give secure, tool-friendly wiring
SIRIUS 3RT23 IEC Contactor
The SIRIUS 3RT23 IEC magnetic contactor provides four-pole switching for motor control circuits. It operates on a 110-120V AC coil and mounts on DIN rail or surface for panel integration. Two auxiliary contacts (1NO/1NC) support signalling and interlock functions in industrial automation.
Sustained Load Ratings
The contactor handles 16 A full-load inductive current and 35 A resistive current continuously. Non-reversing operation suits single-direction motor starters and heating loads. Screw terminals secure conductors for reliable connections under vibration. The S0 frame size fits standard industrial enclosures without forced-air cooling.
Four-Pole Interface Limits
Four poles switch three-phase lines plus neutral or two separate two-phase circuits. Coil voltage range of 110-120V AC matches common control transformers. No enclosure rating means the unit requires a rated cabinet for environmental protection. Overall dimensions of 5.1 in height by 4.4 in width determine panel spacing.

Questions about this item
How much heat does the 16 A inductive load generate during continuous duty?
At the rated 16 A inductive current the contactor dissipates heat inside its 5.1 in tall frame; normal panel ventilation keeps the coil and contacts within IEC limits.
What control voltage and coil terminals must my panel already provide?
The coil requires 110 V to 120 V AC and connects via the screw terminals on the SIRIUS 3RT23 frame.
Will the 4.4 in wide S0 housing fit on the same DIN rail as my legacy starters?
Yes, the S0 frame mounts on standard DIN rail or surface, so it aligns with older contactors that share the same rail spacing.
