Siemens 3MT8400-1AF07 Contactor AC-3, 400A/200kW, 400V, 4NO4NC, 110 VAC, 50 Hz, 3-pole, size S12 Original Brand New

Overview

The Siemens 3MT8400-1AF07 is a robust and high-performance AC-3 contactor designed for heavy-duty industrial applications. Engineered by Siemens, a global leader in industrial automation, this 3-pole contactor is built for reliability and efficiency in switching operations for motors and other inductive loads. With a formidable current rating of 400A and a power rating of 200kW at 400V, it is ideally suited for demanding environments requiring precise control of high-power machinery. Its compact size S12 frame and convenient screw terminals ensure straightforward installation and integration into existing systems.

Function

The primary function of the Siemens 3MT8400-1AF07 contactor is to safely and efficiently switch electrical power to a load, typically an electric motor. It acts as an electrically controlled switch, allowing for remote or automated control of high-current circuits. When the 110 VAC, 50 Hz control voltage is applied to the coil, the main contacts close, providing power to the connected equipment. Conversely, when the control voltage is removed, the contacts open, disconnecting the power. The inclusion of 4 NO (Normally Open) and 4 NC (Normally Closed) auxiliary contacts provides extensive flexibility for interlocking, signaling, and control circuit integration.

Key Feature

• High Power Rating: Capable of handling 400A AC-3 current and 200kW at 400V, making it suitable for large motors and heavy industrial loads.
• 3-Pole Design: Ideal for controlling three-phase electrical systems.
• Versatile Auxiliary Contacts: Features 4 Normally Open (NO) and 4 Normally Closed (NC) auxiliary contacts for enhanced control and monitoring capabilities.
• Coil Voltage: Operates with a standard 110 VAC, 50 Hz control voltage, ensuring compatibility with common industrial control systems.
• Robust Construction: Siemens quality engineering ensures durability and long operational life in demanding industrial environments.
• Screw Terminals: Provides secure and reliable electrical connections, simplifying wiring and installation.
• Compact Size S12: Optimized design for efficient use of panel space.
• AC-3 Utilization Category: Specifically designed for switching squirrel-cage motors during operation, which involves making and breaking current while the motor is running.
