Siemens 3RT2944-5NE31 Magnetic Coil 48-80V AC/DC with Integrated Varistor for 3RT2.4 Contactor Original Brand New

Overview

The Siemens 3RT2944-5NE31 is a high-performance replacement or spare magnetic coil (solenoid coil) designed specifically for the SIRIUS 3RT2.4 series power contactors, corresponding to Contactor Size S3. This essential industrial control component is engineered for AC/DC wide voltage operation, reliably functioning across a range of 48 V to 80 V AC/DC at both 50 Hz and 60 Hz.

A critical feature is the integrated varistor, which provides superior surge suppression, protecting both the coil and the wider control circuitry from damaging voltage spikes. This ensures high operational reliability and extends the lifespan of your contactor system.
