Descrizione del prodotto

In 3-phase systems with neutral often also single phase loads are connected between phase and neutral. If the neutral is missing in a system like this, unsymmetric voltages occur, that could damage single phase consumers, if the voltage rises to high. Also consumers can stop to work if the phaseneutral voltage gets too low. The IL 9069 detects this problem and can switch off the system immediately.
