Phase selection relay with display RVF-3-63A PROxima EKF RVF-3-63a (8012421669)

The RVF-3 EKF PROxima phase selection relay is used to power a single-phase 230V/50(60) Hz load from a three-phase four-wire (five-wire) network. The relay switches the power supply to a single-phase consumer depending on the availability and quality of the phase voltage on conductors L1, L2 and L3. The highest priority is to supply the load from the phase conductor L1, less priority from L3, at normal voltage parameters in all phases, the relay will connect the load from the priority phase (L1). If the voltage value in the priority phase exceeds the thresholds, the device switches the load to another phase. If the voltage on the standby phases does not correspond to the set thresholds, the load is switched off by the phase selection relay RVF-3 EKF PROxima is used to supply a single-phase load of 230V/50(60) Hz from a three-phase four-wire (five-wire) network.
