Schneider Electric Zelio control relay for 3-phase detection of phase-loss and

Zelio RM17 is a compact series of control relays which is easy to mount on a DIN-rail.The relays are available for either 1 phase or 3 phase applications and are able to measure the voltage, current, phase-loss, phase-sequence and asymmetry between phases.With a width of only 17,5 mm they only take up a very limited space on the DIN-rail and they also fit behind the cover of a standard panel.RM17TG20 is a simple control relay for phase-loss and phase-sequence in 3-phase applications.The 3 phases are mounted on the supply L1, L2 and L3 terminals on the top of the relay and the output contacts are located in the bottom.The output is activated instantanious when powered on if all 3 phases are present and mounted in the right order.The control relay has 2 C/O output contacts and the maximum load is 5A.RE17TG20 is self powered through the measuring terminals on the top and the supply voltage can be from 208 to 440 VACThe relay can be used with both 50Hz and 60Hz supply voltage.A yellow LED on the front of the relay indicates the relay output status.
