Siemens SIRIUS 3RT2934-5AN21 Magnetic Coil 220V AC, 50/60 Hz For Contactor Size S2 Original Brand New

Overview

The Siemens 3RT2934-5AN21 is a high-quality, genuine replacement solenoid coil specifically designed for the SIRIUS 3RT2 generation of power contactors, particularly those in Size S2 (Model types 3RT203., 3RT233., and 3RT253.). This essential component is crucial for the electrical operation of the contactor, providing the necessary electromagnetic force to actuate the contacts.

Engineered with precision by Siemens, this magnetic coil guarantees compatibility and long-term reliability for demanding industrial applications. It operates on a standard control supply voltage of 220 V AC with dual frequency compatibility (50/60 Hz), making it versatile for global use.

Benefit

1. Guaranteed Compatibility: As a genuine Siemens spare part, it ensures perfect fit and seamless operation with SIRIUS 3RT2 contactors (Size S2).
2. Reliable Performance: Maintains the original switching performance and operational integrity of your motor starter or control application.
3. Wide Frequency Use: Operates reliably on both 50 Hz and 60 Hz power systems without the need for a separate coil.
4. Minimizes Downtime: Quick and easy replacement ensures minimal interruption to your production or system operation.

Function & Application

The 3RT2934-5AN21 coil serves as the electromechanical actuator within the contactor assembly. When the 220 VAC control voltage is applied, the coil generates a magnetic field that pulls the armature, closing the main power contacts and allowing current to flow to the load (e.g., an electric motor). It is a vital component for:

• Motor Control Centers (MCCs)
• Industrial Automation Systems
• HVAC and Pumping Applications
• Any system using Siemens 3RT2 Size S2 contactors for reliable load switching.
