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

Zelio control relay 3-phase for measuring phase break and phase sequence 2 C/O 5A 3x230-400 VAC Product description: Zelio RM17 is a series of compact control relays that can easily be mounted on a DIN rail. The series is available for either single-phase or three-phase applications and can be used to measure voltage, current, or phase break/phase sequence and asymmetry. With a width of only 17.5 mm, they take up very little space on the DIN rail, just like they fit under a cover on a distribution board. RM17TG20 is a simple phase sequence and phase break relay for three-phase applications. The three phases are mounted on the L1, L2, and L3 terminals at the top of the relay with the contact set at the bottom. The output is activated immediately upon supply if all three phases are present and installed in the correct order. The control relay has two C/O outputs that can be loaded up to 5A.RM17TG20 is powered directly through the measurement circuitry and can be used for both 50Hz and 60Hz supplies.A yellow LED on the front of the relay indicates that it has been pulled in (activated).
