Ensure precise electrical automation and network tracking within your control panels without paying full retail distributor expenses. This fully verified, pre-owned Siemens 3UG4501-1AW30 SIRIUS Monitoring Relay provides professional industrial-grade control logic, systematically opening and closing critical circuit paths to protect secondary hardware components from sequence anomalies, faults, or voltage issues.
| SPECIFICATION / VALUE | DETAILS & BENEFITS |
|---|---|
| Item Condition | USED — Thoroughly inspected second-hand automation hardware. The non-conductive compact outer housing is fully structural, rear DIN-rail snapping clips are intact, lower screw terminals are clean, and the front analog calibration potentiometers turn cleanly with exact tactile feedback. Made in Czech Rep. |
| Product Type | SIRIUS series industrial electrical network monitoring and automation control relay block. |
| Model / Part Reference | 3UG4 Series / Part Number 3UG4501-1AW30 (Conforms strictly to international industrial codes including IEC/EN 60947-5-1 and GB14048.5 at 50/60Hz grid standards). Certified by UL, CE, EAC, KC, and C-Tick marks. |
| Adjustable Delay Controls | Features front panel calibration dials enabling technicians to manually optimize response thresholds and set precise operational time delays (scaled from 0.1s to 10s) to prevent false trips during transient electrical spikes. |
| Contact Configuration | Equipped with 1 Changeover Contact (1 CO dry relay contact layout). Supports auxiliary command ratings of B300 and R300 under UL guidelines. Rated under AC-15 at 3A (24V to 240V) and DC-13 up to 1A at 24V. Max protective fuse line capability of 4A gL/gG. |
| Insulation & Voltage Limits | Rated Insulation Voltage (Ui) of 300V with a high-capacity Rated Impulse Withstand Voltage (Uimp) capacity of 4 kV. Designed to operate safely in ambient surrounding air temperatures up to 60°C. |
| Wiring & Integration | Compact 22.5mm slimline profile optimizes sub-distribution panel spacing. Features terminal tracks accommodating solid or stranded multi-wire layouts from AWG 20 to 14, calibrated to a recommended tightening torque of 7 to 10.3 lb-in (0.8 to 1.2 N.m). |
| Value Advantage | Genuine European-built engineering by Siemens. High-quality bimetallic and solid-state internal components withstand intense vibration and continuous industrial thermal loads, eliminating the risk of volatile software freezes. Provides a highly cost-effective and dependable choice for immediate maintenance inventory. |
