• Eliminates need for level sensors to detect dry
running.
• For 3-phase motors from 1 to 630 A and over.
Cable feed through relay itself.
• Precise motor heating and cooling memory,
reproduces its thermal image.
• Visual indication of tripping cause.
• Adjustable reset time for cos

Suitable for 3-phase submersible pumps, petrol
station pumps, and other type of pumps and
systems where running without load is critical (dry
well, broken transmission belt, etc.).
