• Easy Wiring: Features reliable screw terminals for secure and straightforward main and auxiliary circuit wiring.
• Global Compliance: Approved for worldwide use (e.g., IEC and UL/CSA) and is IE3/IE4-ready, supporting energy-efficient motor solutions.
• Integrated Auxiliary Contacts: The built-in $1\text{ NO}+1\text{ NC}$ contacts reduce complexity and wiring effort, providing immediate feedback for control circuits.
• Seamless Integration: Fully compatible with a wide range of accessories and other components in the SIRIUS modular system, such as overload relays and function modules.

Function and Application

The 3RT2036-1AB00 functions as the primary electrical switch in a motor feeder. When the $24\text{ V AC}$ control voltage is applied to the coil, the main power contacts close, allowing the 3-phase power to flow to the motor.

Typical applications include:

• Switching 3-phase AC motors (Direct-On-Line starting)
• Controlling resistive loads in heating systems
• Integration into complex motor control centers (MCCs)
• Full-Voltage Non-Reversing (FVNR) starters
• General power switching in industrial automation and low-voltage installations
