The Siemens 3RT2924-5AU21 is a genuine replacement or spare magnetic coil specifically designed for use with the SIRIUS 3RT2 series of power contactors, in particular the Size S0 models: 3RT2023-.A, 3RT2024-.A, and 3RT2025-.A. This essential component, also known as a solenoid coil or magnet coil, is engineered to operate reliably on a 380 V AC control supply voltage at both 50 Hz and 60 Hz frequencies, ensuring compatibility across various international electrical standards. As a critical spare part, the 3RT2924-5AU21 maintains the performance and safety standards of your Siemens control system.
The magnetic coil is the core actuation component of an electromechanical contactor. When the specified control voltage (380 V AC, 50/60 Hz) is applied to the Siemens 3RT2924-5AU21 coil, it generates a magnetic field. This field pulls the armature, causing the contactor's main and auxiliary contacts to close or open, thereby safely controlling the power supply to a connected load (e.g., a motor). This function is vital for starting, stopping, and controlling electrical circuits in automation and control systems.
