Product Positioning

The 3RT1965-5AV31 is a replacement operating mechanism used in Siemens SIRIUS large contactors 3RT106 and 3RT146. Functionally equivalent to a general coil assembly, it is used to drive the main contacts of the large contactor to hold and release. It supports 380-420VAC/DC, 50/60Hz universal power supply, uses screw terminal wiring, and has a built-in energy-saving circuit design. After holding, it reduces continuous power consumption and heat generation, making it an original factory replacement option for large contactor coil aging or burnout.

Core Product Advantages and Features
Wide AC/DC compatibility
Control voltage 380-420V, supports AC 50/60Hz and DC operation, adaptable to different control circuit power supply types.
Built-in power-saving circuit
It features an economizer power-saving circuit design that automatically reduces power consumption and heat generation after the suction action is completed.
Screw terminal wiring
It uses standard screw terminal connections, making on-site wiring and replacement operations intuitive and convenient.
Compatible with 3RT106/3RT146 series
The size and drive characteristics are designed specifically for SIRIUS 3RT106 and 3RT146 large contactors. It is recommended to check the original model when replacing them.
