Siemens 3MT8025-1AP03 Contactor AC-3, 25A/11kW, 400V, 1NO1NC, AC 230V, 50Hz, size S0 Original Brand New

Overview

The Siemens 3MT8025-1AP03 is a robust and reliable AC-3 contactor, an essential component for controlling electric motors and other inductive loads in industrial and commercial applications. Engineered for performance and durability, this size S0 contactor is rated for 25A (up to 11kW at 400V) and features a versatile 230V AC coil, making it suitable for a wide range of power control systems. Its compact design and convenient screw terminals ensure straightforward installation and maintenance.

Function

The primary function of the Siemens 3MT8025-1AP03 contactor is to safely and efficiently switch high current electrical circuits on and off, typically for electric motors. When the 230V AC control voltage is applied to the coil, an electromagnetic field is generated, pulling the main contacts together to establish a power connection. Conversely, when the control voltage is removed, the contacts open, disconnecting the power. This rapid and reliable switching mechanism protects equipment from overloads and provides remote or automated control capabilities. The integrated 1NO (normally open) and 1NC (normally closed) auxiliary contacts offer additional signaling and interlocking options for complex control circuits.
