Siemens 3RT2944-5AV01 Magnetic Coil 400 V AC 50 Hz for Contactors 3RT2.4-.A Original Brand New

Overview

The Siemens 3RT2944-5AV01 is a genuine SIRIUS magnetic coil engineered for high-performance industrial control applications. Specified for 400 V AC at 50 Hz, this coil is designed to fit seamlessly into Siemens 3RT2.4 series power contactors (type S3) and deliver dependable switching operation in demanding electrical systems.

Function

• The magnetic coil acts as the solenoid drive for the contactor’s armature. When 400 V AC (50 Hz) is applied, it generates the magnetic field necessary to actuate the contactor’s main contacts.

• When the coil is de-energized, the magnetic field collapses and the contacts open, ensuring the safe interruption of the load circuit.

• It is an essential spare or replacement part within the Siemens 3RT2.4 system, enabling reliable switching of motors, loads or control circuits in industrial installations.

Benefit

• Exact OEM match: Designed specifically for the Siemens 3RT2.4 series contactors ensuring perfect compatibility and optimum performance.

• High reliability in industrial use: Built to withstand rigorous environments, offering long service life in automation systems.

• Efficient system maintenance: Enables the replacement of worn or failed coils in existing contactor installations — reducing downtime and cost compared to full contactor replacement.

• Global supply standard: As part of the Siemens SIRIUS portfolio, you can trust the product quality, availability and support infrastructure worldwide.
