Siemens 3MT8050-1AN24 Contactor AC-3, 50A/22kW, 400V, 2NO2NC, 220 VAC, 50/60 Hz, 3-pole, size S2 Original Brand New

Overview

The Siemens 3MT8050-1AN24 is a robust and reliable 3-pole AC-3 contactor, meticulously engineered for demanding industrial applications. Designed for motor control up to 22 kW at 400V, this S2 size contactor features a highly efficient 220V AC 50/60 Hz coil for precise and dependable operation. Its versatile 2 normally open (NO) and 2 normally closed (NC) auxiliary contacts provide enhanced control and signaling capabilities, making it an ideal choice for a wide range of switching tasks in automation and power distribution systems. With its convenient screw terminals, installation and wiring are straightforward, ensuring a secure and lasting connection.

Function

The Siemens 3MT8050-1AN24 contactor serves as an electromagnetic switch for controlling electrical power circuits, particularly those connected to electric motors. When the 220V AC coil is energized, it creates a magnetic field that pulls the main contacts together, allowing the flow of high current to the connected load. Conversely, when the coil is de-energized, the contacts open, interrupting the circuit. The integrated 2NO+2NC auxiliary contacts offer additional functionality, enabling interlocking, signaling, and control circuit integration. This contactor is specifically rated for AC-3 utilization category, making it perfectly suited for switching squirrel-cage motors during operation, where breaking occurs while the motor is running.
