Benefit

• High Performance for Motor Control: With a robust $225\text{ A}$ current rating and $110\text{ kW}$ capacity at $400\text{ V}$, this contactor is ideal for switching high-power three-phase asynchronous motors.
• Future-Proof (IE3/IE4 Ready): Complies with the latest efficiency standards through the $\text{AC-3e}$ utilization category, ensuring compatibility with highly-efficient motors.
• Vibration-Proof Wiring: The use of spring-loaded terminals for the control and auxiliary circuits significantly reduces wiring time and provides a highly reliable, maintenance-free connection, even in environments with high vibration.
• Flexible Integration: Features a conventional drive and busbar connections for the main circuit, allowing seamless integration into existing industrial systems and motor feeders.
• Reliable Monitoring: Integrated $\text{2 NO}+2\text{ NC}$ auxiliary contacts offer clear status feedback for essential interlocking and control functions in your industrial automation systems.
• Modular SIRIUS System: Benefit from the wide range of coordinated accessories and compact design of the Siemens SIRIUS family for easy expandability and space-saving installation.

Function

The 3RT1064-2AD36 functions as a primary power switching device in industrial controls. It is energized by a 42-48 V AC/DC control signal, which magnetically closes the three main power contacts to connect or disconnect a three-phase load (like a motor) from the $400\text{ V}$ power supply. The spring-loaded terminals ensure the coil and auxiliary circuit connections remain secure.
