Siemens SIRIUS 3RT1064-6LA06 Power Contactor, Size S10, 225A, 110kW/400V, 3-Pole Original Brand New

Overview: High-Performance SIRIUS 3RT1 Power Contactor

The Siemens SIRIUS 3RT1064-6LA06 is a robust, 3-pole power contactor from the SIRIUS modular system, engineered for superior switching of motors and high-current loads up to 225 A in industrial applications. Designed for the demanding AC-3e/AC-3 utilization category, this contactor offers a high-performance solution for switching motors up to 110 kW at 400 V.

It is delivered without an operating mechanism (coil), allowing for flexible selection of the required control voltage. The Size S10 design is built for durability and high switching reliability, even in harsh industrial environments.

Benefits & Features

• Exceptional Power Handling: Rated at 225A and 110kW (at 400V) for heavy-duty motor control and switching applications.
• IE3/IE4 Motor Ready: Complies with the modern AC-3e utilization category, making it ideal for the reliable switching of high-efficiency motors.
• Modular SIRIUS System: Seamlessly integrates with the vast range of Siemens SIRIUS components and accessories for quick and easy system expansion.
• High Reliability: Engineered for a long mechanical and electrical service life, minimizing downtime and maintenance costs.
• Integrated Auxiliary Contacts: Features built-in 2 NO + 2 NC contacts for simple wiring of control and signaling circuits.
• Flexible Integration: Main circuit utilizes busbar connections for robust power distribution, while control circuits use reliable screw terminals.

Function & Application

The Siemens 3RT1064-6LA06 is primarily used in industrial automation to:

1. Switch 3-Phase Motors: Start, stop, and reverse large three-phase asynchronous motors in pumps, compressors, fans, and conveyor systems.
2. Control Resistive Loads (AC-1): Ideal for switching heaters, lighting, and general power circuits with a rating up to 275A (AC-1, 400V).
3. Implement Safety Functions: The integrated auxiliary contacts are crucial for feedback and interlock circuits in complex control systems.
