The 3UG4615-1CR20 is a digital 3-phase voltage monitoring relay detecting phase failure, sequence, undervoltage, and overvoltage with adjustable delays of 0.1 to 20 s. It operates from 160 to 690 V AC at 50 or 60 Hz and has two changeover contacts rated at 3 A at 250 V AC and 1 A at 24 V DC. The device mounts via snap-on rail with dimensions of 92 mm height, 22.5 mm width, and 91 mm depth, using screw terminals for 0.5 to 4 mm² solid or 0.5 to 2.5 mm² stranded conductors. It meets IP20 protection, operates from -25 to +60 °C, and is rated for installation up to 2000 m altitude. Galvanic isolation is provided between input, output, and supply circuits.
