The Siemens SIRIUS 3UG4983-1A voltage reducer module extends the supply voltage range of the 3UG4583 insulation monitoring relay to 690 V AC and 1000 V DC. It handles line frequencies from 15 to 400 Hz. Mounting is straightforward: it snaps onto a 35 mm DIN rail in any position, and connections are made via screw-type terminals accepting 0.75 to 2.5 mm² stranded wire with ferrules. The IP20 protection class means it's intended for installation inside an enclosed control panel, not in wet or dusty environments.
