Siemens 3MT8400-1AM07 Contactor AC-3, 400A/200kW, 400V, 4NO4NC, 220 VAC, 50 Hz, 3-pole, size S12 Original Brand New

Overview

The Siemens 3MT8400-1AM07 is a high-performance, 3-pole AC-3 contactor engineered for demanding industrial power switching applications. Designed for motor control and resistive loads, this robust device handles significant current and power, making it ideal for heavy machinery, pumps, fans, and other critical industrial equipment. Its precise specifications, including a 400A current rating and 200kW power handling at 400V, ensure reliable and efficient operation in a wide range of electrical systems. Built with Siemens’ renowned quality and durability, the 3MT8400-1AM07 provides a dependable solution for controlling high-power loads.

Function

The Siemens 3MT8400-1AM07 contactor serves as an electrically operated switch, primarily for making and breaking power circuits. When the 220 VAC, 50 Hz control voltage is applied to its coil, the electromagnetic force pulls the main contacts together, allowing the high-current power circuit to flow. Conversely, de-energizing the coil opens the contacts, safely interrupting the power. Its 4 normally open (NO) and 4 normally closed (NC) auxiliary contacts provide versatile signaling and interlocking capabilities for control circuits, enabling complex automation and safety functions within your electrical system. This contactor is specifically rated for AC-3 utilization, making it perfect for standard AC motor switching where breaking occurs while the motor is running.
