Entes MK-01 Phase Failure Device, also known as a motor protection relay. This device is designed to monitor 3-phase motors and protect them from damage caused by phase faults, voltage unbalance, and overheating.
It provides protection against phase failure, phase sequence failure, and asymmetry.
The relay is suitable for use in industrial plants and other applications involving 3-phase motors.
It operates without a neutral connection and has a fixed asymmetry setting of 20%.
The operating voltage is 230 VAC, and it features a contact output of 8A, 2000 VA.
