The CAH-01 phase sequence sen-
sor device is used to protect devices
powered three-phase installation (e.g. a
motor) from being damaged in case of
phase voltage switch off or phase voltage
asymmetry. The threshold value switch
on is preset to 185 V and it can’t be re-
gulated by the user. The system does not
