Siemens AG Monitor - Relay Output 3UG4513-1BR20

The 3UG4513-1BR20 is a SIRIUS network monitoring relay for phase failure, sequence, and asymmetry detection in AC systems from 160 to 690 V at 50 to 60 Hz. It has two change-over contacts with screw terminals, adjustable delay from 0 to 20 seconds, and 5% measurement precision. Mounting is snap-on, with dimensions of 92 mm height, 22.5 mm width, and 91 mm depth. It operates from -25 to +60 °C, is rated IP20, and provides galvanic isolation. The output relay supports 3 A at 250 V AC and 1 A at 24 V DC. Mechanical life is 10 million cycles; electrical endurance is 100,000 cycles at AC-15. EMC compliance includes IEC 61000-4-2, -4-4, and -4-5.
