Siemens 3MT8025-1AQ00 Contactor: AC-3, 25A/11kW, 400V, S0, Screw Terminal, 380V 50Hz Original Brand New

Overview

The Siemens 3MT8025-1AQ00 is a robust and reliable AC-3 power contactor, engineered for efficient switching of motors and other demanding AC loads in industrial and commercial applications. As part of Siemens’ renowned SIRIUS modular system, this size S0 contactor offers a compact design, high performance, and exceptional contact reliability, making it a cornerstone for modern control systems. Featuring convenient screw terminals, it ensures secure and straightforward wiring for both main and control circuit.

Function

The Siemens 3MT8025-1AQ00 contactor is primarily used for switching three-phase squirrel-cage motors under AC-3 utilization category conditions. This means it’s ideal for applications where the motor is started and stopped while running, handling the inrush current effectively. Its main function is to make and break the connection of power to an electrical load, acting as an electrically operated switch. The 380V AC, 50Hz coil energizes the electromagnet, closing the main contacts and allowing current to flow to the connected equipment.
