Verify before ordering. The AC-3 current rating is inconsistent across public listings (17 A versus 25 A) and could not be reconciled against a Siemens original datasheet. Motor power has therefore been omitted. Confirm all values against the Siemens SIRIUS 3RT2 technical data before publishing or quoting this item.

Description

The Siemens 3RT6025-1AN20 is a three pole SIRIUS power contactor for AC-3 motor duty on 400 V supplies, with an AC 220 V 50/60 Hz coil. It carries three normally open main contacts and one normally open plus one normally closed auxiliary contact, and includes a mirror contact function for safety feedback per IEC 60947-4-1. The device mounts on a 35 mm DIN rail and accepts the standard SIRIUS 3RT2 auxiliary contact blocks and surge suppression modules. Typical duties are conveyor drives, pumps, compressors, chillers and general machine control circuits.

  • Mirror contact for safety related feedback
  • AC 220 V 50/60 Hz coil
  • 35 mm DIN rail or screw fixing
  • Accepts SIRIUS 3RT2 auxiliary blocks and RC suppressors

Series Information

3RT2Siemens platform overview

The SIRIUS 3RT2 range is the current Siemens power contactor family, covering S00, S0, S2 and S3 frame sizes. All frames share the same auxiliary contact blocks, surge suppression modules and mechanical interlocks, and all offer screw or spring (push-in) connection. Frame sizes up to S2 are commonly used in machine control, pumping and HVAC, while S3 and above serve heavy motor starting duty.

FAQ

Is the 3RT6025-1AN20 new and original?
Yes. Parts are sourced from authorized distributors and original manufacturers and ship in original packaging.
Can I use this contactor for a safety function?
The device includes a mirror contact that can be used for feedback monitoring. The overall safety function must be designed and validated for your machine.
Which auxiliary contact blocks fit?
The standard SIRIUS 3RT2 auxiliary contact blocks for the matching frame size. Tell us the contact configuration you need and we will add it to the quote.
Do you supply the matching overload relay?
Yes. Send the motor full load current and we will quote the matching 3RU2 thermal overload relay with the correct setting range.
