• Voltage Compatibility: Operates with a 400VAC, 50 Hz control voltage.
• 3-Pole Design: Suitable for three-phase motor control and other multi-phase applications.
• Integrated Auxiliary Contacts: Includes 1 Normally Open (1NO) and 1 Normally Closed (1NC) auxiliary contact for flexible control circuit integration.
• Compact Size S2: Optimized dimensions for space-saving installation in control cabinets.
• Reliable Screw Terminals: Provides secure and easy wiring connections.
• Durable Siemens Quality: Built to Siemens’ high standards for long-lasting performance and reliability in industrial environments.

Function

The Siemens 3MT8065-1AV03 contactor functions as an electrically controlled switch, primarily used for remotely controlling and switching power circuits, typically for electric motors. When the 400VAC, 50 Hz coil is energized, it creates an electromagnetic field that pulls the main contacts closed, allowing current to flow to the connected load (e.g., a 30kW motor). When the coil is de-energized, the contacts open, interrupting the power flow. The integrated 1NO1NC auxiliary contacts provide feedback and control signals to other parts of the system, enabling interlocking, status indication, and more complex control logic.

Benefit

• Enhanced System Control: Enables remote and automated control of high-power equipment, improving operational efficiency and safety.
• Increased Equipment Lifespan: Protects motors and other inductive loads from overloads and transient currents, extending their operational life.
• Space Efficiency: The compact S2 design allows for more efficient use of space within control panels and electrical enclosures.
• Easy Installation & Maintenance: Screw terminals simplify wiring, reducing installation time and making maintenance more straightforward.
• Reliable Performance: Backed by Siemens’ reputation for quality and engineering excellence, ensuring consistent and dependable operation in demanding industrial settings.
• Versatile Application: Ideal for a wide range of industrial applications including motor control, lighting systems, heating, and power distribution.
