Siemens Phase, Voltage Monitoring Relay, 3 Phase, DPDT, 160 → 690V ac, DIN Rail / 5187051

Line Supply and Three Phase Voltage. 3UG4 relays that monitor current, power factor and active current are ideal for monitoring the load of motors and functionality of electronic loads. These devices detect the effect of wear and faults early on. This means that appropriate actions can be taken before more significant damage occurs. . Wide voltage range versions reduce inventory stock levels Variable settings for over-range, under-voltage or window monitoring Delay times and reset switch Actual value and fault types are permanently displayed Removable terminals 22.5mm wide 3UG4614 to 3UG4617 can be digitally set, with fault memory and LDC display 1-20V hysterisis Phase failure (except stock no ; 518-7275 518-7275 )
