Product Positioning

The 3RT2023-1AC20 is a representative model of the low-voltage coil in the Siemens SIRIUS 3RT2023 series. It is an S0 frame 3-pole contactor with an AC-3 rated current of 9A, capable of handling a 4kW/400V three-phase motor load. The coil is rated for 24V AC and is compatible with 50Hz and 60Hz power supplies. It features 1 NO + 1 NC instantaneous auxiliary contacts, making it suitable for general applications where safety considerations for control voltage are important and excessive auxiliary contacts are not required. It is a common entry-level choice for low-voltage control panels.

Core Product Advantages and Features
24V AC dual-frequency coil
The 24V AC coil supports both 50Hz and 60Hz power supplies, making it suitable for different regions to use the same part number.
1NO+1NC basic auxiliary contact
It has a built-in set of normally open and a set of normally closed instantaneous auxiliary contacts to meet the basic self-holding or indicating circuit requirements.
Low-voltage control is safer
The 24V low-voltage coil design reduces the risk to operators and maintenance personnel when they come into contact with the control circuit.
The S0 base is easy to integrate.
It shares the same base size as the 3RT2023 series, making it compatible with existing panel designs and mounting hole positions.
