Siemens SIRIUS 3UG4617-1CR20 digital monitoring relay for three-phase line voltage. It monitors all three phases of a 160 to 690 V, 50/60 Hz supply for overvoltage, undervoltage, phase asymmetry, phase failure and phase sequence, with automatic phase sequence correction. Two changeover contacts, LCD showing measured value and parameter, powered from the measured line. One relay.
3UG4 — Siemens SIRIUS monitoring relay family.
6 — digital three-phase line-voltage group with LCD.
17 — function set with automatic phase sequence correction.
1C — screw terminal connection.
R20 — measuring range 3 x 160 to 690 V AC.
Function: Digital three-phase line voltage monitoring relay. Series: SIRIUS 3UG4. Measuring Range: 3 x 160–690 V AC, 50/60 Hz. Monitored Conditions: overvoltage, undervoltage, phase asymmetry, phase failure, phase sequence with automatic correction. Asymmetry Setting: 0–20 percent. Hysteresis Setting: 1–20 V. Off Delay: 0–20 s. Output: 2 changeover contacts. Display: LCD. Supply: powered from the measured line. Terminals: Screw terminals. Mounting: 35 mm DIN rail. RoHS: compliant. Unit Quantity: 1 Pc.
Width: 22.5 mm, DIN rail unit with screw terminals. The three line conductors connect directly to the measuring inputs; no separate control supply. Settings are made with the front buttons and read on the LCD.
Siemens 3UG4615-1CR20 has the same measuring range and terminal arrangement without automatic phase sequence correction. Variants ending R21 and other R-codes cover different measuring ranges.
3 x 160 to 690 V AC, 50/60 Hz.
Overvoltage, undervoltage, phase asymmetry, phase failure and phase sequence, with automatic phase sequence correction.
Two changeover contacts.
