    Applications
    Used in air conditioning units, elevator machine room, pumps, fans and other motor control applications, as protection of over-voltage, under voltage, phase failure, phase sequence, phase imbalance and PTC temperature. When the power supply is abnormal, turn off power supply to protect the equipment.
    Features:
    Built-in microprocessor, true RMS measurement, measurement accuracy≤1%. 50/64Hz universal, knob setting, LED indicator shows working status. Withe N-phase phase failure protection, unique load-side and PTC temperature protection, optional manual reset and key test function, DIN rail mounting.
