Siemens 3RT2944-5AV61 SIRIUS Contactor Magnet Coil, 480V AC, 60Hz, Size S3 Original Brand New

Overview: Siemens 3RT2944-5AV61 SIRIUS Magnet Coil

The Siemens 3RT2944-5AV61 is a high-quality, genuine replacement magnet coil designed specifically for the SIRIUS 3RT2.4 series of power contactors (typically Size S3). This essential component ensures the correct electrical operation of the contactor, enabling it to switch electrical loads (like motors) efficiently.

Operating at a control supply voltage of 480 V AC and a frequency of 60 Hz, this coil is crucial for maintaining the performance and reliability of your industrial control system, particularly in North American standard applications. It belongs to the SIRIUS family of industrial controls, known for their durability and high performance.

Function

The primary function of the 3RT2944-5AV61 magnetic coil is to generate the magnetic force required to actuate the armature within the Siemens 3RT2.4 contactor. When the specified 480 V AC, 60 Hz control voltage is applied to the coil terminals, it pulls the armature, closing the main power contacts and allowing current to flow to the load. Removing the control voltage de-energizes the coil, releasing the armature and opening the contacts. This reliable switching mechanism is fundamental for motor control and industrial automation.
