Overview
The Siemens 3MT8140-1AV07 is a high-performance, robust AC-3 Contactor designed for reliable switching of resistive and inductive load in industrial applications. As part of Siemens’ trusted electrical component, this 3-pole contactor is engineered for demanding environment, offering exceptional durability and operational efficiency. With a rated current of 140A and a power rating of 75kW at 400V, it is perfectly suited for controlling powerful motor, heating element, and other heavy-duty electrical equipment. Its compact Size S6 design ensures efficient use of panel space, while the intuitive screw terminals facilitate straightforward installation.
Function
The Siemens 3MT8140-1AV07 Contactor serves as an electrically controlled switch used for switching an electrical power circuit. It functions by establishing or interrupting a high-current circuit using a low-power control signal. When the 400VAC, 50Hz control voltage is applied, the electromagnetic coil within the contactor pulls the main contact together, allowing power to flow through the 3-poles. Conversely, when the control voltage is removed, the contacts open, interrupting the circuit. The integrated 4 Normally Open (NO) and 4 Normally Closed (NC) auxiliary contact provide versatile signaling and interlocking capabilities for complex control system.
