Product Positioning

The 3RT1965-5NP31 is an electronic operating mechanism (reversing operating mechanism) used in Siemens SIRIUS large contactors 3RT106 and 3RT146. Unlike ordinary simple electromagnetic coils, this module has an electronic drive circuit, and the control power supply can be 200 to 277VAC/DC, 50/60Hz universal. It also provides a 24VDC screw terminal interface for PLC to directly send action signals. It is suitable for automation applications that require precise control of large contactor holding/releasing by a programmable controller.

Core Product Advantages and Features
Electronic drive architecture
It adopts an electronic operating mechanism design, rather than a traditional simple electromagnetic coil, to provide more precise motion control.
Wide-range control voltage
The power supply supports 200-277VAC/DC and is universally compatible with 50/60Hz, adapting to different power supply environments.
Low continuous power consumption
With a holding power of approximately 530VA and a holding power of only approximately 5VA, it generates less heat and consumes less energy during operation.
PLC signal input directly
It provides a 24VDC screw terminal interface, which can be directly driven by PLC output signals, facilitating automation integration.
