Product Positioning

The 3RT2023-1AD00 is a low-voltage coil S0 frame 3-pole contactor in the Siemens SIRIUS 3RT2023 series. It has an AC-3 rated current of 9A and can handle a 4kW/400V (up to 7.5kW at 690V) three-phase motor load. The coil specifications are 42V AC, 50Hz. It is a common choice for control circuits with high safety requirements and where reduced operating voltage risks are necessary, such as handheld or near-person control panels. The contactor has 1 NO + 1 NC auxiliary contacts built-in, and both main and auxiliary circuits use screw terminals for connection. It has a mechanical life of approximately 10 million operations, meeting the needs of production lines with long-term, frequent operation.

Core Product Advantages and Features

42V AC low voltage coil

It adopts a 42V AC, 50Hz low-voltage coil design, which is suitable for control circuits with safety requirements for operating voltage.

690V can reach 7.5kW

The main circuit can carry a maximum three-phase motor load of 7.5kW under 690V power supply, and is flexible to adapt to different power supply levels.

1NO+1NC auxiliary contact

It has a built-in set of normally open and a set of normally closed instantaneous auxiliary contacts for easy interlocking and signal feedback wiring.

Long mechanical life

With a mechanical life of approximately 10 million operations, the AC-4 still has a life of approximately 200,000 operations under heavy load, making it suitable for applications with frequent start-stop cycles.
