Product Positioning

The 3RT2023-1AP00 is the most basic and common standard model in the Siemens SIRIUS 3RT2023 series. Its coil voltage is AC230V, 50Hz, corresponding to the single-phase 230V control power supply commonly used in most Taiwanese switchboards. The main circuit has three sets of normally open (NO) main contacts, with an AC-3 rated current of 9A and a rated power of 4kW/400V, suitable for direct start-stop control of general three-phase asynchronous motors. The auxiliary contacts are standardly equipped with 1 NO + 1 NC instantaneous contacts, which can be used for operating status feedback and stop interlock signals, respectively. Both the main and auxiliary circuits use screw terminals for easy installation and future maintenance by general electricians. As it is the most basic combination in the series, it is usually the model with the most stable spare parts inventory and delivery time.

Core Product Advantages and Features

AC230V standard coil

It is compatible with the common single-phase 230V control power supply in Taiwan and can directly drive the coil without the need to install a control transformer.

3 sets of normally open main contacts

The main circuit is a 3NO configuration, AC-3 rated 9A, 4kW/400V, suitable for direct start and stop of general three-phase motors.

1NO+1NC auxiliary contact

It comes standard with one set of normally open and one set of normally closed instantaneous contacts, which can simultaneously provide operation feedback and interlock protection functions.

Stable material preparation and fast delivery

As the most basic style in the series, its inventory and delivery time are usually more stable than other special coil versions.
