Phase control relay

Control relay of presence or phase unbalance and contractor status control

Used for protection of electromotors and electricity-generating equipment connected to three-phase networks in case of absence of voltage at least in one phase, voltage brownout, voltage unbalance and contractor contact brake.

Control relay of presence or phase unbalance

Used for protection of electromotors and electricity-generating equipment connected to three-phase networks in case of absence of voltage at least in one phase, voltage brownout, voltage unbalance.

Control relay of presence or phase unbalance and phase sequence

Used for protection of electromotors and electricity-generating equipment connected to three-phase networks in case of absence of voltage at least in one phase, voltage brownout, voltage unbalance and phase sequence break.

Phase Control relay for networks with insulated neutral

Для защиты электродвигателей и электроустановок, подключённых к трёхфазной сети, в случаях: отсутствия напряжения хотя бы в одной из фаз, снижения напряжения меньше установленной величины, асимметрии напряжения, нарушения чередования фаз.
