Siemens SIRIUS 3RT1064-2AF36 Power Contactor, 225A, 110kW, AC/DC 110-127V Coil, 3-Pole, S10 Size Original Brand New

Overview: High-Performance Siemens SIRIUS 3RT1 Power Contactor

The Siemens 3RT1064-2AF36 is a robust, high-performance power contactor from the modular SIRIUS 3RT1 series, specifically engineered for switching high-power motors in industrial applications. Rated for 225 A at AC-3 and handling up to 110 kW at 400 V, this 3-pole contactor is a crucial component for motor control and protection.

A key feature is its conventional AC/DC wide-range coil (110–127 V AC/DC), offering flexibility and simplifying logistics. It is designed for secure, high-current main circuit connection via busbars and features convenient, vibration-proof spring-loaded terminals for the control and auxiliary circuits.

Benefit

• Reliable High-Power Motor Switching: The 225A / 110kW rating ensures dependable operation for large, demanding motor loads in heavy-duty industrial environments.
• Reduced Wiring Time: The innovative spring-loaded terminals on the control and auxiliary circuits provide fast, vibration-proof, and maintenance-free connections, drastically lowering installation costs compared to screw terminals.
• Global Compatibility (AC/DC Coil): The wide-range 110–127 V AC/DC control coil provides maximum flexibility, allowing for use in both AC and DC control systems with a single component.
• Modular SIRIUS System: Seamlessly integrates with other SIRIUS components, simplifying the design and assembly of complex load feeders.
• Long Service Life: Engineered for exceptional endurance with a mechanical service life of up to 10 million operating cycles, reducing downtime and replacement frequency.
• High Safety Standards: Comes with pre-installed 2 NO + 2 NC auxiliary contacts for reliable signaling and interlocking in the control circuit.

Function

The Siemens 3RT1064-2AF36 is an electromechanical contactor designed for switching 3-phase AC motor loads. Upon energizing the 110-127 V AC/DC control coil, a magnetic force closes the 3 main Normally Open (NO) power contacts, supplying power to the motor. Simultaneously, the integrated 2 NO and 2 NC auxiliary contacts change state, providing feedback and control signals to the higher-level automation system (e.g., a PLC). The busbar main circuit connection is ideal for high-current applications, ensuring a robust and efficient power path.
