Siemens 3RT2924-5AC01 Magnetic Coil 32V AC, 50Hz, SIRIUS S0 Contactor Original Brand New

Overview

The Siemens 3RT2924-5AC01 Magnetic Coil is an essential and genuine spare part for the Siemens SIRIUS 3RT2 generation of power contactors, specifically those in Size S0. This coil is engineered to deliver reliable and precise electromechanical actuation for your motor control applications. Operating on a 32 V AC, 50 Hz control supply voltage, it is the direct replacement for use with 3RT2023-.A, 3RT2024-.A, and 3RT2025-.A motor contactors. Utilizing this original Siemens component ensures optimal performance, longevity, and seamless compatibility within your SIRIUS modular system.

Function

The magnetic coil is the heart of the contactor. When the specified control voltage (32 V AC, 50 Hz) is applied, the 3RT2924-5AC01 coil generates the magnetic field necessary to:

1. Pick-up: Provide the mechanical force to rapidly close the main power contacts of the linked 3RT202 contactor.
2. Hold: Sustain the magnetic force to keep the contacts closed for continuous, reliable operation until the control voltage is removed.

Benefit & Features

• Optimal Compatibility: Designed as a direct, perfect-fit replacement for Siemens 3RT202 Contactor models, guaranteeing quick installation and zero compatibility issues.
• Reliable Performance: Ensures consistent and safe switching operations with its specified 32 V AC, 50 Hz control voltage and precise power ratings (65 VA pick-up, 7.6 VA holding).
• Durable SIRIUS Quality: Manufactured under Siemens’ rigorous standards for a long service life and high reliability in demanding industrial environments.
• Reduced Downtime: Quick replacement of a faulty coil minimizes production interruptions and maintenance time.
• Standard Compliance: The product is part of the SIRIUS modular system, ensuring adherence to global electrical and safety standards.

Application

This coil is typically used in industrial automation and electrical control systems for:

• Replacing worn or damaged coils in existing 3RT202 series contactors.
• Spare parts inventory for critical motor starters and control circuits.
• New installations where a 32V AC, 50Hz control circuit is required for Size S0 contactors.
