Manhua 3 Phase and neutral 230VAC, protect motor from phase failure and voltage unbalance MK-01 Phase Failure Device

Description:

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