Siemens AG Monitor - Relay Output 3UG46332AL30

The 3UG4633-2AL30 is a digital voltage monitoring relay for AC/DC systems from 17 to 275 V, designed to detect overvoltage and undervoltage conditions in single-phase and DC circuits. It features a 22.5 mm width, snap-on mounting, and a height of 94 mm with a depth of 91 mm. The device includes one changeover contact with spring-type terminals supporting conductor cross-sections of 0.25 to 1.5 mm². It operates from -25 to +60 °C, has an insulation voltage of 690 V for overvoltage category III, and withstands a 4 kV surge voltage. The relay offers adjustable delay times from 0.1 to 20 s, hysteresis from 0.1 to 150 V, and a relative repeat accuracy of 1%. It meets IEC 60664 and IEC 61000-4-3/4-4/4-5 standards for electromagnetic compatibility and is rated for 10,000,000 mechanical switching cycles and 100,000 electrical cycles at AC-15, 230 V.
