Power Electronics Asymmetry Monitor Three-Phase PT433-8

Suitable for protecting asynchronous three-phase motors from anomalies in the electric power distribution network. Monitors the voltage of the three-phase network regarding the loss of one or more phases or the neutral. Monitors the asymmetry of the three phases (adjustable 5-25%), as well as their overvoltage and undervoltage.
