Phase sequence relay RP32
3-phase phase sequence / phase breaking module
Monitors correct phase sequence
Secures against phase breaking
1- or 2-pole relay output
AC supply voltages up to 3 x 415 VAC
Made in accordance with the
and EMC regulations
The C-mac® module type RP32 meters its own 3-phase Connections RP32:
supply voltage, and checks that all 3 phases are present
L1
and the phase sequence is correct, and in that case the output relay is activated.
The module is suitable for the monitoring of motors, as it
5
ensures correct rotation, and in case of a missin phase the
4
relay releases, provided that the possible regenerated voltage from the motor is below the fixed minimum limits..
3
The module can be used both with and without neutral,
2
but with neutral the unit is most sensitive.

Approvals: The units are produced in accordance with the CE
og low voltage regulations.
Sensitivity:
If the unit is connected to 3 phases with neutral, the relay will
release, if one or more of the phase-neutral voltages is lower
than 75-85% of the nominal voltage.
If the unit is connected to 3 phases without neutral, the relay will
release, if one or more of the phase-phase voltages is lower than
60-70% of the nominal voltage
