It monitors AC/DC systems for both overvoltage and undervoltage conditions across a rated value range of 24 to 240 V at 50 or 60 Hz, with a measurable voltage range extending from 10 to 600 V AC. The relay offers a relative repeat accuracy of 1 %, making it suitable for applications where tight voltage window control is needed — think motor protection, generator monitoring, or supply quality supervision in a control panel. The output contact ratings are 1 A at 24 V, 0.2 A at 125 V, and 0.1 A at 250 V. These are low-level signal contacts — not for switching motor loads or solenoids directly. Use this relay to signal a PLC input or a contactor coil; anything heavier needs an interposing relay. The relay supports both automatic reset (auto-RESET,) and external reset, with isolation between the outputs and between input and output. That means you can wire a remote reset button on the panel door and still keep the control circuit isolated from the monitored voltage.","metaTitle":"Siemens 3UG4632-2AW30 SIRIUS Voltage Monitoring Relay, 24-24","metaDescription":"Siemens 3UG4632-2AW30 SIRIUS voltage monitoring relay, 24-240 V AC/DC, LCD display, over/undervoltage detection, 1% repeat accuracy, IP20.
