Meters - Three-phase voltmeter RH-3AV63 Digital Panel REHE — Digital panel meter for switchboard fronts, with a three-digit display, used for live monitoring of three-phase current or voltage. Ammeters are normally fed from a current transformer and the CT ratio must match the setting inside the meter, otherwise readings are scaled high or low; direct-connection types cover small ranges only. Voltmeters are wired for line or phase voltage, so confirm the system nominal voltage matches the meter range before connecting. Isolate the panel before mounting, align the cut-out with the bezel and secure with the clips; the auxiliary supply voltage must match the nameplate. Jumping readings usually come from loose terminals or interference, so check the terminals before blaming the meter. Check the model (RH-3AA63 current / RH-3AV63 voltage), range and ratio before ordering.
