Monitoring applications = phase, voltage
Supply voltage = 160 → 690 Vac
Contact arrangement = 2-pole changeover switch
Voltage sensitivity = Undervoltage
Electrical phases = 3
Voltage measuring range = 160 → 690 Vac
Sensitivity of the phase = phase asymmetry, phase failure, phase sequence
Delay time = 0.1 → 20 s
Length = 91mm

Supply voltage and three-phase voltage. 3UG4 Relay for monitoring current, power factor and active current, ideal for monitoring motor loads and the functionality of electronic loads. These components anticipate the effects of wear and failures. In this way, the appropriate measures can be taken before serious damage occurs. Versions with a wide voltage range reduce the requirements for spare parts inventory. Variable settings for overrange, undervoltage or window monitoring Delay times and reset switches Actual value and error types are permanently displayed Removable terminals 22.5 mm wide 3UG4614 to 3UG4617 can be set digitally, with error memory and LDC display 1-20 V hysteresis Phase loss (except order no. ; 518-7275 518-7275 ).
