Fanox PS-R – Single-Phase Pump Protection Relay

The Fanox PS-R relay provides complete protection for single-phase pump motors from 3 to 16 A. By monitoring undercurrent, it detects dry running, cavitation, and flow failure conditions without the need for float switches or level sensors — delivering a highly reliable and cost-effective protection solution.

  • Single-phase pump protection via undercurrent monitoring
  • Current range: 3–16 A
  • No level sensors required to detect dry running
  • Precise thermal-image memory for heating and cooling cycle control
  • Visual LED indication of tripping cause
  • Adjustable reset time for undercurrent (I<) threshold
  • Protects against dry running, cavitation, and similar fault conditions

The PS-R is ideal for domestic booster pumps, small irrigation pumps, light commercial water systems, and any single-phase pump application where reliable protection without level sensors is required.
