Product Positioning

3RT1934-5AF01 is a 110V AC control coil for Siemens SIRIUS S2 size contactors, suitable for production line equipment using 110V as the control circuit voltage. When only the coil of the contactor fails and the main body structure is still intact, this part number can be selected to complete the repair, avoiding the high cost of replacing the entire unit.

Core Product Advantages and Features

AC110V specification

The rated voltage is AC 110V, which is suitable for machine tool designs that use 110V as the control circuit voltage.

Corresponding to S2 size contactor

Specifically designed for the repair and replacement of large contactors in the Siemens SIRIUS S2 size 3RT10 series.

Screw terminal connection

The screw terminal fixing method makes on-site wiring and replacement operations intuitive and convenient.

Original factory registered part number

This is a standard part number officially registered with Siemens, not a coil assembled from parts or a counterfeit product from a third-party manufacturer.

Quick Replacement and Repair

The coil can be disassembled and replaced independently, eliminating the time and cost of replacing the entire contactor group.

Professional selection service

Kenxin Motors assists in verifying coil voltage and contactor model to avoid malfunctions caused by incorrect installation specifications.
