3-phase by COS φ PF-R does not need level sensors to detected dry running. It is designed for use with 3-phase motors from 1 to 630 A and over. It has a cable feed, visual indicator of the tripping cause, adjustable reset time for cos φ, and timer module PF-RM. Unit has accurate motor heating and cooling memory that will reproduce the thermal image. The unit is commonly used in domestic, industrial and agricultural applications that include submersible pumps (water supply, well dewatering, irrigation, petrol stations) and surface pumps (sewage treatment plants, pressure sets, swimming pools, fire-fighting equipment). It can be used with other applications that need monitoring such as ventilators, belt drives or conveyor belts.
