TH218 Series Phase Failure Relay

Using advanced large-scale integrated circuits, the TH-218, TPNG, TPLC and TPL series of phase failure relays feature a small volume, high precision, reliable action, low power consumption, long service life, large contact capacity and easy installation. They are widely used in a variety of automatic control systems for liquid level control and phase reversal, phase failure, phase unbalance, overvoltage and undervoltage detection.
