• Eliminates need for level sensors to detect dry running.
• For 3-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.
• Manual, remote and automatic reset.
Suitable where the undercurrent (running without load) is
critical, such us submersible pumps, surface pumps, etc. In
these cases, when the equipment runs without load (dry well)
the relay trips by undercurrent.

these cases, when the equipment runs without load (dry well)

The great advantage of the P relay is that, without requiring
any external detectors such as level electrodes, it monitors the
load of the motor and stops it before an expensive breakdown
occurs.

By means of this plug-in optional accessory, the relay status
can be seen and reset from the exterior of the electrical panel
