CZF-311 PHASE LOSS AND ASYMMETRY SENSOR 10A 1P 1M 3X400/230V+N AC
High-quality phase loss and asymmetry sensor, ideal for protecting electric motors powered from a three-phase network.
Application
The phase loss sensor protects the electric motor from damage due to voltage loss in at least one phase or voltage asymmetry between phases. With an adjustable voltage asymmetry threshold, it ensures the stability of the device’s operation.
