Siemens AG Monitor - Relay Output 3UG45112AP20

The 3UG4511-2AP20 is a phase sequence monitoring relay for AC control voltages between 320 and 500 V at 50 or 60 Hz, with a single change-over contact and LED indication. It features spring-type terminals for connectable conductor cross-sections of 0.25 to 1.5 mm² and is designed for snap-on mounting with dimensions of 84 mm height, 22.5 mm width, and 91 mm depth. The relay provides galvanic isolation between input, output, and supply circuits, operates within -25 to +60 °C, and has an electrical endurance of 100,000 switching cycles at AC-15-230 V. It meets IEC 60664 insulation standards for overvoltage category III and complies with IEC 61000-4-2, -4-3, -4-4, and -4-5 for electromagnetic compatibility.
