          Applications

          Used in air conditioning units, elevator machine room, pumps, fans and other motor control applications, as protection of over-voltage. Uunder 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.

          Note:

          1. "+"Function is available, "-"Function is not availble. "○"Function can be customized.

          2. In three-phase four-wire circuit, relay without phase sequence protection could acheive sigle-phase or two-phase protection.

          3. Choose either PTC protection or load protection.

          4. Load protection: L1/L2/L3(P-P).
