Siemens 3MT8140-1AF04 Contactor AC-3, 140A, 75kW, 400V 3-Pole, S6 Size 110V AC Coil Original Brand New

Overview

The Siemens 3MT8140-1AF04 is a robust and high-performance AC-3 contactor, meticulously engineered for demanding industrial applications. Designed to switch resistive and squirrel-cage motor load up to 140 Amperes (75 kW at 400V), this 3-pole contactor is a vital component for motor control, automation, and power distribution system. Its compact yet powerful Size S6 construction ensures reliable operation and efficient space utilization within control panel.

Function

The Siemens 3MT8140-1AF04 contactor functions as an electrically operated switch that controls the flow of power to a connected load, typically an electric motor. When the 110 VAC coil is energized, it creates a magnetic field that pulls the main contacts closed, allowing power to flow. De-energizing the coil opens the contacts, interrupting the power. The integrated 2 NO and 2 NC auxiliary contacts provide crucial signaling for control circuits, allowing for interlocking, status indication, and advanced automation functions.
