Neutral Monitor
IL 9069

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.

Features
. According to IEC/EN 60255-1
. Detection of
- missing neutral in the system
- broken neutral on IL/SL 9069
- neutral exchanged against phase
. Detection of phase failure also with disconnected load
. For 3-phase systems
. De-energized on trip
. LED indicator for operation/state of output contacts
. Single phase connection possible
. Without auxiliary voltage
. 2 cangeover contacts
. Optionally with adjustable asymmetry detection and on delay
