Three-phase voltage measuring and monitoring relay
RP33
COMADAN
Built-in adjustable time-delay
Separate adjustments for minimum and maximum limits
1-pole relay output 8 A / 250 V AC
AC supply voltages up to 3 x 415 VAC
Made in accordance with the CE and EMC regulations
The C-mac® module type RP33 meters its own 3-phase supply voltage, and checks that all 3 phase-neutral voltages are within the adjusted limits, and in that case, the output relay is activated.
If one or more of the voltages are over or under the limits for a period of time, which exceeds the set delay, the relay releases.
The module can operate from 80 to 120% of the nominal supply voltage.
