1-phasemonitoring relay
Monitoring of 1-phase supply voltage
Separate adjustment of min. and max. limits
1-2 pole relay output
Supply: Select variant

3 – phase monitoring of own supply voltage
The C-mac® RP30 measures its own supply voltage and checks that all phase voltages are within the adjusted limits, and in that case the output relay is activated.
If one more of the voltages are over or under the limits, the relay releases
Note: If a measurement of 3 phases with zero is desired, type RP33 must be used (see separate data sheet)
