Product Positioning

The 3RT1054-1NP36 is a Siemens SIRIUS 3RT10 series S6 frame large three-pole power contactor. It also adopts an electronic operating mechanism, with a wide control voltage range of 200-277V AC/DC and an optional 24V DC PLC interface. It belongs to the same electronic family as the 2NP36, but the difference lies in the terminal type: the main circuit box-type terminal is combined with screw-type auxiliary terminals, making installation and wiring intuitive and reliable.

Core Product Advantages and Features

Electronic operating mechanism

By replacing traditional coils with electronic circuits, the operation becomes more stable and power consumption is reduced.

200-277V AC/DC wide voltage range power supply

A single part number covers multiple control power supply voltages, simplifying selection and material preparation.

24V DC PLC interface optional

It can be directly driven by PLC output signals, eliminating the need for intermediate relays.

Box-type main terminal + screw auxiliary terminal

The main circuit box-type terminals are paired with screw-type auxiliary terminals, ensuring stable wiring.
