One of the common faults faced in industrial plants is over-heating and burning of 3 phase motors due to the phase failure. Thermic-magnetic device” which is an essential element in motor protection is generally too slow due to both its electromechanical structure and the use of high current setting range to assure demarrage without tripping. Being designed to eliminate the above disadvantages, MKC-01 and MKC-03 Phase Failure Devices react within 0.2 seconds (fixed) against the following faults and take the motor out of service.
