Phase asymmetry relay RP31 - COMADAN - #1

"IIICIC Phase asymmetry relay RP31

The C-mac® module type RP33 meters its own 3-phase supply voltage, and if the phase sequence is correct and the phase asymmetry is below the adjusted level, the out­put relay is activated.

The module is suitable for monitoring of motors, since it ensures correct rotation direction and releases in case ofa missing phase, also if the motor continues its rotation, provided that the resulting asymmetry is higher than the adjusted limit.

To ensure the best possible monitoring, the module must be connected as close to the motor as possible, in this way, Connections RP31_: the contactor function is also monitored.
