Siemens 3RT2924-5AN21 SIRIUS Magnetic Coil, 220V AC, 50/60Hz, for S0 Contactors (3RT2023, 3RT2024, 3RT2025) Original Brand New

Overview

The Siemens 3RT2924-5AN21 is a genuine spare part, high-performance AC magnetic coil designed for use with the SIRIUS range of Siemens 3RT2 power contactors. Specifically engineered for Size S0 motor contactors (models 3RT2023-.A, 3RT2024-.A, and 3RT2025-.A), this coil is crucial for the reliable operation of the contactor, enabling it to open or close the main power circuit. It operates on a standard control supply voltage of 220 V AC at both $50\text{ Hz}$ and $60\text{ Hz}$ frequencies.

Benefit

• Reliable Performance: Ensures consistent and dependable operation of your Siemens 3RT2 Size S0 contactor.
• Optimal Compatibility: Guaranteed fit and electrical compatibility with the specified 3RT2023-.A, 3RT2024-.A, and 3RT2025-.A contactors.
• Durable Design: Manufactured by Siemens, the coil meets rigorous quality standards for long service life in industrial applications.
• Easy Replacement: Designed for straightforward installation and replacement in the field, minimizing downtime.
• Dual Frequency: Operates efficiently on both $50\text{ Hz}$ and $60\text{ Hz}$ control systems.

Function and Application

The magnetic coil is the core component of an electromechanical contactor. When the $220\text{ V AC}$ control voltage is applied to the 3RT2924-5AN21 coil, it generates a magnetic field. This field overcomes the spring force, pulling the armature to close the main contacts of the coupled 3RT2 contactor, thereby allowing power to flow to a motor or other load (up to $7.5\text{ kW}$ in the S0 size). It is an essential spare part for maintenance and repair of industrial motor control systems, ensuring the continued functionality of the main contactor.
