Siemens 3RT2924-5AQ21 Magnetic Coil 500 V AC 50/60 Hz, Compatible with 3RT202 Contactors Original Brand New

Overview

The Siemens 3RT2924‑5AQ21 is a high-performance magnetic coil designed for the SIRIUS Series contactors from Siemens. It provides a control supply voltage of 500 V AC, at both 50 Hz and 60 Hz, and is engineered to work specifically with contactor models 3RT2023-.A, 3RT2024-.A, and 3RT2025-.A in the Size S0 range.

Key Features & Function

• Operates at 500 V AC control voltage for both 50 Hz and 60 Hz systems, allowing compatibility with higher-voltage industrial control circuits.

• Directly compatible with Siemens SIRIUS contactors 3RT2023-.A, 3RT2024-.A, 3RT2025-.A (Size S0) – simplifying maintenance and replacement tasks.

• Robust design for long service life in demanding industrial applications: built to Siemens quality standards.

• Screw-terminal connection for secure installation within motor control panels.

• Supports the modular SIRIUS system architecture, ensuring seamless integration with existing Siemens control gear.

Benefit

• Reduced downtime: With direct compatibility and straightforward installation, you can replace the coil quickly and resume operations sooner.

• High reliability: The coil meets stringent industrial standards, designed to perform under continuous duty and varied conditions.

• Flexibility: The 500 V AC rating gives greater voltage margin and allows use in different electrical environments.

• OEM compatibility: As an original Siemens component, it preserves the performance characteristics of the contactor assembly.

Application

• Motor control centres where the contactor is switching motors up to 7.5 kW (Size S0) under 500 V AC control supply voltages.

• Industrial automation panels, HVAC systems, manufacturing machinery, and other setups using Siemens SIRIUS contactors.

• Maintenance and repair of electrical control systems where the original coil has failed or needs replacement due to aging or voltage change.
