Siemens 3MT8018-1AH00 Contactor AC-3, 18A/7.5kW, 400V, W/O, AC 48V, 50Hz, size S0 Original Brand New

Overview

The Siemens 3MT8018-1AH00 is a robust and reliable AC-3 contactor, specifically designed for controlling electric motors and other resistive loads in industrial and commercial applications. This Size S0 contactor is engineered for efficiency and durability, capable of handling up to 18 Amperes (AC-3) and providing 7.5 kW of power at 400V. Its compact design and screw terminals ensure straightforward installation and maintenance, making it an ideal choice for various control circuits.

Function

The Siemens 3MT8018-1AH00 functions as an electrically operated switch, primarily used for remotely controlling the flow of high current in a circuit. When the 48V AC, 50Hz control voltage is applied to its coil, the contactor’s main contacts close, allowing power to flow to the connected load (e.g., an electric motor). When the control voltage is removed, the contacts open, disconnecting the load. This mechanism provides safe and efficient control, protecting equipment from overloads and facilitating automation.
