ManHua Protect Motor From Phase Failure Phase Sequence reserve voltage unbalance 3 phase 220V MKC-05 Phase Failure device

Description:

One of the common faults faced in industrial plants is overheating and damaging 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 hing current setting range to assure demarrage without tripping.Being designed to eliminate the above disadvantages,MKC-05 Phase Failure Devices serve the following protection features：Phase failure,Phase sequence,Voltage unbalance,Insufficient supply.
