Siemens 3RT2944-5AN61 SIRIUS Magnet Coil, S3 Frame, 200V AC, 50Hz/220V AC, 60Hz, Replacement Contactor Original Brand New Coil

Overview

The Siemens 3RT2944-5AN61 is a genuine replacement SIRIUS Magnet Coil for use with the Siemens 3RT2.4 Series Power Contactors (typically Size S3). This essential component ensures reliable and efficient operation by generating the necessary magnetic force to actuate the contactor’s armature. Operating on a dual frequency AC control supply voltage of 200 V AC at 50 Hz or 220 V AC at 60 Hz, this coil is crucial for maintaining the performance of your industrial control and motor switching applications, particularly in regions where these voltages and frequencies are standard.

Function

The primary function of the 3RT2944-5AN61 magnetic coil is to provide the electrical force needed to close (or open) the main power contacts within the compatible contactor. When the specified 200 V (50 Hz) or 220 V (60 Hz) AC control voltage is applied to the coil terminals, it energizes, pulling the armature and switching the electrical load, such as a motor. When de-energized, the armature releases, opening the contacts. This provides the fundamental ON/OFF switching mechanism for motor control centers and industrial automation systems.
