Product details

Coil for SIRIUS contactors, 110 V AC

The 3RT5935-5AG21 is a SIRIUS magnet coil for Siemens contactors, rated 110 V AC at both 50 Hz and 60 Hz. It uses a screw connection for the control wiring. The coil's operating range at 50 Hz is 0.8 to 1.1 times the rated voltage — meaning it pulls in reliably between 88 V and 121 V, which covers typical brownout conditions on a 110 V control transformer.
