Product Positioning

The 3RT2023-1AF00 belongs to 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. Unlike the dual-frequency models in the same series, this part number has a coil specification of 110V AC, 50Hz single frequency, suitable for production lines and equipment with a fixed power frequency of 50Hz. The unit also features 1NO+1NC auxiliary contacts for easy connection to control circuits or signal feedback. It has a rated insulation voltage of 690V, a withstand impulse voltage of 6kV, and multiple certifications including CE, UL, CSA, and CCC, making it suitable for export-oriented panel applications.

Core Product Advantages and Features

50Hz single-frequency coil

The 110V AC 50Hz coil design is suitable for use in existing factories or production lines with a fixed power frequency of 50Hz.

1NO+1NC auxiliary contact

It has a built-in set of normally open and a set of normally closed instantaneous auxiliary contacts to meet the needs of self-holding or interlocking control.

High impulse voltage resistance design

With a rated insulation voltage of 690V and an impulse withstand voltage of up to 6kV, it improves the reliability of power supply under surge conditions.

Multiple international certifications

Certifications such as CE, UL, CSA, and CCC are obtained, and the equipment complies with relevant EAC regulations, which facilitates cross-border equipment procurement and verification.
