Product Positioning

The 3RT2023-1AL20 is a coil version of the Siemens SIRIUS 3RT2023 series specifically designed for dual-frequency power grids. It operates at AC 230V and covers 50Hz (0.8~1.1 times rated voltage) and 60Hz (0.85~1.1 times rated voltage). A single coil can adapt to different regional power grid frequencies, which is highly advantageous for export-oriented equipment or cross-plant material preparation. The main circuit AC-3 has a rated current of 9A and a rated power of 4kW/400V. At 690V, the rated power increases to 7.5kW while maintaining a rated current of 9A. The auxiliary contacts are standardly equipped with 1NO+1NC instantaneous contacts. Both main and auxiliary circuits use screw terminals, capable of handling 1~10mm² wires. The dimensions are 85 x 45 x 97 mm, with a mechanical life of 10 million cycles and a 690V insulation voltage and 6kV impulse voltage withstand capability. Its overall specifications are consistent with the main models in the series, making it a reliable choice for dual-frequency applications.

Core Product Advantages and Features

AC230V Dual-Frequency Coil

The operating range covers 50Hz and 60Hz, and the same coil can be used for different regional power grid frequencies, eliminating the need for frequency division and component preparation.

AC-3 9A/4kW, 690V up to 7.5kW

At 400V, the rated current is 9A and the power is 4kW; at 690V, the power increases to 7.5kW, while maintaining the rated current of 9A.

1NO+1NC auxiliary contact

The standard configuration includes one normally open and one normally closed instantaneous contact, along with screw terminals, for convenient signal feedback and interlocking wiring.
