The 0... 690 V AC measurable voltage range covers standard low-voltage networks up to 690 V phase-to-phase, common in industrial distribution. The 15... 400 Hz line frequency acceptance means the module can monitor not just 50/60 Hz mains but also the output of VFDs running at higher carrier frequencies — a real advantage when the insulation relay needs to see the actual motor cable condition, not just the line side. Spring-loaded terminals (push-in style) accept solid conductors 2x (20... 16 AWG) and stranded 2x (18... 16 AWG), or finely stranded 0.5... 1.5 mm² with or without core end processing. No screwdriver needed for termination, which speeds panel wiring and reduces torque-verification steps during commissioning. The 45 mm width (roughly 2.5 standard module slots) fits a compact footprint alongside the 3UG4583 relay. No UL, CSA, or CE marking is explicitly listed in the available data, so verify jurisdictional acceptance if your panel requires those marks.","metaTitle":"Siemens SIRIUS 3UG4983-2AA01 Voltage Reducer Module, 0-690 V","metaDescription":"Siemens SIRIUS 3UG4983-2AA01 voltage reducer module for 3UG4583 insulation monitoring relay.
