Siemens 3RT1064-2AM36 Power Contactor, 225A AC-3e/AC-3, 110kW 400V, 3-Pole with 2NO + 2NC Contacts Original Brand New

Overview

The Siemens 3RT1064-2AM36 Power Contactor is a high-performance switching device designed for reliable motor control and industrial automation applications. Built with Siemens’ advanced engineering, this 3-pole contactor ensures maximum durability, efficiency, and safety in demanding electrical environments. With a rated operating current of 225 A (AC-3/AC-3e) and power handling of 110 kW at 400 V, it delivers robust performance for medium to large-scale electrical installations.

Benefits & Key Features

• High Performance: Efficiently switches motors up to 110 kW and handles high currents up to 225 A, meeting both AC-3 and the energy-efficient AC-3e standards.
• Flexible AC/DC Operation: The 200-220 V coil accepts both AC and DC control voltages, simplifying inventory and system design.
• Fast, Secure Wiring: Spring-loaded terminals on the control and auxiliary circuits ensure fast, tool-free, and maintenance-free wiring, even in high-vibration environments.
• Integrated Auxiliary Contacts: The built-in 2 NO and 2 NC auxiliary contacts provide ready-to-use signaling and interlocking capabilities, minimizing external component requirements.
• SIRIUS Modular System: Seamless compatibility with the SIRIUS modular system, allowing for easy expansion with accessories like overload relays and more.
• IE3/IE4 Ready: Optimized for switching the latest generation of highly efficient IE3 and IE4 motors.

Function

The Siemens 3RT1064-2AM36 functions as an electromechanical switching device primarily used for switching three-phase AC motors and resistive loads in industrial control systems. When the coil is energized by the 200-220V AC/DC supply, the main 3-pole contacts close, connecting power to the load (e.g., motor). The integrated auxiliary contacts switch state simultaneously, providing feedback or enabling complex control sequences. The robust Size S10 design is specifically for heavy-duty applications.

Application

Ideal for integration into motor starters, distribution boards, and industrial machinery for applications such as:

• Switching 3-phase AC motors (pumps, fans, compressors)
• Basic motor control circuits
• High-current resistive load switching (e.g., heating elements)
• Integration into complex automation and control panels.
