monitoring relay RP33
| 3-phase monitoring of phase-neutral
voltages 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-macŪ 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. |
