RM35 TF multi-function three-phase network control relays
RM35 TF30 measurement and control relays for 3-phase supplies monitor correct sequences of phases L1, L2 and L3, as well as total loss of one or more phases, asymmetry, as well as over- and undervoltage with independent adjustments.
It produces multi-voltage products that accept different three-phase voltage values from 220 → 480 Vac.
It checks its own power supply, measured in true RMS values.
Fitted with a clear hinged front cover to prevent any accidental alteration of settings.
Voltage between phases is selected by a potentiometer on the front.
LED display of output status.
For mounting on DIN rail.
