Zelio™ Phase Measurement Relays
RM17TG•0
Zelio Phase Measurement Relays monitor their own power supply. Relay status is
indicated by an LED and they are DIN rail mountable.
RM17TG•0 measurement and control relays are for monitoring of 3-phase supplies for
the correct sequencing of phases L1, L2, and L3, as well as the total loss of one or more
phases.
