Product Positioning

The 3RT2023-1AG24 is a standard 3-pole contactor with an S0 base in the Siemens SIRIUS 3RT2 series. It has an AC-3 rated current of 9A and can handle a 4kW/400V three-phase motor load. The coil is 110V AC and supports both 50Hz and 60Hz frequencies, allowing for simplification of parts planning for equipment in different regions by using the same part number to accommodate different power supply environments. The mechanism also incorporates four sets of instantaneous auxiliary contacts (2NO + 2NC), which can be directly used for interlocking, indicator lights, or PLC signal feedback circuits, saving the time and cost of purchasing additional auxiliary contact modules.

Core Product Advantages and Features

Dual-frequency coil design

The 110V AC coil supports both 50Hz and 60Hz power specifications, allowing machines across regions or for export to use the same part number, reducing the complexity of material preparation.

4 sets of built-in auxiliary contacts

It comes standard with 2NO+2NC instantaneous auxiliary contacts, eliminating the need to purchase additional auxiliary contact modules to complete interlocking, warning lights, or control feedback wiring.

S0 frame compatible design

It is compatible with the 3RT2023 series in terms of frame size and mounting hole spacing, and existing panels can be directly compared and replaced or upgraded in terms of specifications.

Screw terminal wiring

Both the main circuit and the auxiliary circuit use screw terminals, which conforms to the wiring habits of most distribution panels in Taiwan, making maintenance and replacement more intuitive.
