Siemens 3RT20231AK60 Electromechanical Contactor
MPN Prefix and Family Context
The part number prefix 3RT2023 places this device in Siemens' SIRIUS 3RT2 series contactors, a mid-range electromechanical switching family used across industrial motor and lighting branch circuits. The trailing 1AK60 designates the coil system — specifically a 120 VAC / 60 Hz control voltage with a must-operate threshold of 96 VAC and a nominal sealing power of 68 VA. These contactors share a common mechanical platform across the 3RT2023 base, with variants differing primarily in coil voltage class and packaging format.
The 3RT20231AK60 provides a 3PST-NO (3 Form A) main pole configuration with one normally open and one normally closed auxiliary contact integrated into the body.

Engineering Verification Checklist
- Control circuit voltage is 120 VAC at the intended operating frequency
- Must-operate voltage of 96 VAC is satisfied under worst-case supply conditions
- Main pole current rating of 9 A covers the connected load at its operating voltage
- Auxiliary contact configuration (1 NO / 1 NC) meets the control scheme requirements
- Panel or enclosure space accommodates the chassis/DIN mounting footprint
- Mechanical clearance is maintained for main power端子 access and wiring
- Operating ambient temperature range (25°C ~ 60°C) encompasses installation conditions
- Bulk packaging format is acceptable for the intended quantity and storage environment
- Coordination with upstream overload protection and downstream loads is reviewed against the specific circuit function

| MPN | Coil Voltage | Must Operate | Coil Power | Similarity |
|---|---|---|---|---|
| 3RT20231AK60 | 120 VAC | 96 VAC | 68 VA | 1.00 |
| 3RT20231AF00 | 110 VAC | 88 VAC | 65 VA | 1.00 |
| 3RT20231AG20 | 110 VAC | 93.5 VAC | 68 VA | 1.00 |
| 3RT20231AP60 | 240 VAC | 192 VAC | 67 VA | 1.00 |
| 3RT20231AV60 | 480 VAC | 408 VAC | 73 VA | 1.00 |
3RT20231AF00 differs in coil voltage class (110 VAC vs 120 VAC) and a slightly lower must-operate threshold (88 VAC), with marginally reduced coil power (65 VA). It may suit 50 Hz systems where 110 V nominal is standard.
3RT20231AP60 targets 240 VAC coil systems with a corresponding must-operate threshold of 192 VAC, sharing the same auxiliary configuration and bulk packaging.
3RT20231AV60 addresses 480 VAC coil applications, with a must-operate threshold of 408 VAC and a higher coil power draw of 73 VA. The main pole rating and mounting remain identical.
