The three-phase monitoring relays CM-PVS.x1 monitor the phase parameters phase sequence, phase failure as well as over- and undervoltage.

All devices are available with two different terminal versions. You can choose between the proven screw connection technology (double-chamber cage connection terminals) and the completely tool-free Easy Connect Technology (push-in terminals).

If the voltage to be monitored exceeds or falls below the set threshold value, the output relays de-energize after the set tripping delay Tv is complete. The LED R/T flashes during timing and turns off as soon as the output relays de-energize. The output relays re-energize automatically as soon as the voltage returns to the tolerance range, taking into account a fixed hysteresis of 5 %. The LED R/T is on.
