MPT Phase Failure (overheat)protector

(overload, overheat, over/under Volt., phase loss, Phase sequence protector)

MPT use PC to detect voltage’s waveform, size, Phase position to decide the voltage is normal or abnormal. It also can quickly detect with inductance load. Available for protection 3 phase equipments for Over/Under volt, Phase Loss. Phase Reversal and overload/overheat protection.
