Fanox P – Pump Protection Relay (3-Phase Undercurrent)
The Fanox P relay protects 3-phase submersible and surface-mounted pumps by detecting dry running through undercurrent monitoring across all three phases simultaneously. When water level drops and the pump runs dry, motor current drops below the preset undercurrent threshold and the relay trips the pump off — preventing damage without any level sensors.
- 3-phase dry-running detection via undercurrent monitoring — no level sensors needed
- Designed for 3-phase motors 1–630 A and over
- Continuous thermal-image memory for complete heat cycle control
- Instant phase-loss detection even at reduced load
- Visual LED indication of tripping cause
- Manual, remote, and automatic reset options
The Fanox P relay controls all three motor supply phases, offering superior reliability over single-phase undercurrent devices that can miss faults on the unmonitored phases.
