Siemens 3MT8012-1AF01 Contactor AC-3, 12A/5.5kW, 400V, 1NO, 110V AC Coil, Size S00, Screw Terminal Original Brand New

Overview

The Siemens 3MT8012-1AF01 is a high-performance 3-pole AC contactor designed for efficient and reliable switching of inductive load, particularly AC motor (AC-3 category). Part of Siemens’ trusted industrial control gear, this compact Size S00 contactor is engineered for demanding applications, offering robust performance and long operational life. With its 12A current rating and 5.5kW power handling at 400V, it’s an ideal solution for a wide range of motor control and industrial automation task. The integrated 110V AC operating coil ensures broad compatibility with standard control circuit, while the secure screw terminal facilitate easy and reliable wiring.

Function

The Siemens 3MT8012-1AF01 contactor primarily functions as an electrically operated switch that controls a power circuit. When the 110V AC coil is energized, it closes the main power contacts, allowing current to flow to the connected load (e.g., an electric motor). The 1NO auxiliary contact provides an additional output for signaling, interlocking, or control circuit feedback. Its AC-3 categorization ensures it can handle the high inrush currents associated with starting AC motors and safely disconnect them under load.
