PEF-301

Universal automatic electronic phase switch PEF-301.

Switch is designed to supply industrial and household appliance single-phase 220V/50Hz loads from three-phase four-wire mains 3x380+N with the purpose of maintaning uninterrupted power supply of essential single-phase loads and protect them against unallowable voltage variations in the mains.

Depending on the voltage presence and voltage quality on phases, the PEF-301 will automatically select the optimal phase and promptly switch the single phase load supply of any wattage to this phase:

  • loads of wattage up to 3 kW (up to 16A) get power supply directly from PEF-301
  • when wattage exceeds 3 kW (16A), PEF-301 phase switch will control the magnetic starters (MS) coils of corresponding wattage (MS can be supplied optionally)

Industrial grade
IP rating IP40, IP20
Operating temperature -35°C to 55°C
