Detail Information
Function
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 and phase unbalance. When the power supply is abnormal, turn off power supply to protect the equipment.
Built-in microprocessor, true RMS measurement, measurement accuracy ≤1%.50/60Hz universal, knob setting, LED indicator shows working status. With N-phase phase failure protection, DIN rail mounting.
