Product Positioning

The 3RT2023-1AN24 is a dual-frequency coil version of the Siemens SIRIUS 3RT2023 series designed for 220V power grids. A single coil can handle both 50Hz and 60Hz power frequencies, making it ideal for export-oriented equipment or devices used across regions, eliminating the need for separate parts preparation based on power grid frequency. The main circuit maintains the consistent standards of the 3RT2023 family, with an AC-3 rated current of 9A and a rated power of 4kW/400V. The auxiliary contacts come standard with four sets of instantaneous contacts (2NO+2NC), doubling the signal points compared to the single-set 1NO+1NC version, suitable for applications requiring multiple functions such as operation feedback, fault warning, and interlock protection. Both main and auxiliary circuits use screw terminals, ensuring compatibility with other models in the series for easy design and maintenance.

Core Product Advantages and Features

AC220V Dual-Frequency Coil

A single coil can simultaneously support 50Hz and 60Hz power grids, making it suitable for export machines or cross-regional applications, eliminating the need for frequency division and component preparation.

2NO+2NC four sets of auxiliary contacts

It provides two sets of normally open and two sets of normally closed instantaneous contacts to meet more complex signal feedback and interlocking requirements.

AC-3 9A/4kW main circuit

It continues the standard rating of the 3RT2023 series, with a current of 9A and a power of 4kW at 400V, and is suitable for general motor start-up and shut-down control.

Compatible with series

Its appearance and installation method are consistent with other coil versions of 3RT2023, which facilitates unified project planning and parts interchangeability.
