Description

Fanox PF 47-R 230V 3-Phase Pump Protection Relay by COS φ
… without Level Sensors!!
Using the motor itself as a sensor and without requiring any external detectors, they monitor the cos φ of the motor and stop it before a breakdown occurs caused by dry running, cavitation or closed valve.
For pumps 10 - 30 hp, 400 Vac
PROTECTION FUNCTIONS:
·
Overload
·
Underload cos φ
·
Phase imbalance or phase loss
·
Phase sequence
Some of the most common applications in domestic, industrial and agricultural installations are as follow:
·
Submersible pumps: water supply, irrigation, well dewatering, petrol stations…
·
Surface pumps: sewage treatment plants, swimming pools, pressure sets, fire-fighting equipment…
·
Other typical applications that require monitoring: belt drives, ventilators, conveyor belts…
Suitable where the undercurrent (running without load) is critical.
·
Without requiring level sensors to detected dry running.
·
For three phase motors from 1 to 630 A and over. Cable feed through.
·
Precise motor heating and cooling memory, reproduces its thermal image.
·
Visual indication of tripping cause.
·
Adjustable reset time for cos φ.
