NEW ARRIVAL: Siemens SIRIUS 3UG4632-1AW30 Voltage Monitoring Relay Now Available
Model Description
We are pleased to announce the immediate availability of the Siemens SIRIUS 3UG4632-1AW30 digital monitoring relay, a compact 22.5mm-wide DIN-rail device engineered for single-phase voltage monitoring in Industrial Automation systems. This advanced relay continuously monitors AC/DC voltages from 10–600V and provides both overvoltage and undervoltage protection with independent adjustable thresholds (0.1–300V hysteresis), making it ideal for generator sets, UPS systems, motor control panels and critical process equipment. The unit operates from a universal 24–240V AC/DC auxiliary supply (50/60Hz) and features one changeover contact (1CO) rated at 5A @ 250V AC, enabling direct control of contactors, alarms or PLC inputs. Screw-clamp terminals accept 0.5–2.5mm² conductors, while integrated LED status indicators and an LCD display simplify commissioning and fault diagnostics. Measuring only 90×22.5×105mm and weighing 137g, the 3UG4632-1AW30 integrates seamlessly into space-constrained control cabinets for packaging, material handling and building automation applications .
Key Features
The 3UG4632-1AW30 delivers exceptional monitoring precision with ±5% voltage accuracy and <250ms response time, meeting IEC 61810-1 standards for reliable protection. The relay provides robust electrical isolation (2.5kV test voltage) and 4kV surge immunity, ensuring stable operation in harsh EMC environments. Selectable start-up bypass delay (0.1–20s) and switch-off delay (0.1–20s) prevent nuisance trips during voltage transients or load changes, while the 0.1–300V hysteresis setting allows fine-tuning for specific application requirements. The device operates reliably from –25°C to +60°C ambient range and carries CE, cULus, CCC, EAC and UL approvals (since September 2014), guaranteeing global acceptance. IP20 finger-safe terminals enhance installer safety, and the maintenance-free design ensures >20-year service life. Gold-plated contacts guarantee reliable low-current switching, making it suitable for modern electronic control systems .
