Magnet Coil for SIRIUS Contactors
The Siemens 3RT5934-5AB01 is a SIRIUS magnet coil designed as a replacement or spare component for compatible contactor frames. It accepts a 24 V AC control supply at 50 Hz, with a voltage tolerance band of 0.8 to 1.1 times the rated value, meaning the coil holds in reliably between roughly 19.2 V and 26.4 V AC. For DC installations, the same coil handles a 30 to 250 V DC range, making it flexible across control architectures without swapping the coil.
