Overview
Solid-state line monitoring relays provide maximum protection
for mobile machines and plants or for unstable networks.
Network and voltage faults can be detected early and rectified
before far greater damage ensues.
Depending on the version, the relays monitor phase sequence,
phase failure with and without N conductor monitoring, phase
unbalance, undervoltage or overvoltage. With the 3UG46 17 or
3UG46 18 relay, a wrong direction of rotation can also be
corrected automatically.
Benefits
• Can be used without auxiliary voltage in any network from
• Variably adjustable to overvoltage, undervoltage or window
• Freely configurable delay times and reset response
• Width 22.5 mm
• Permanent display of ACTUAL value and network fault type on
• Automatic correction of the direction of rotation by

Application
The relays are used above all for mobile equipment, e.g. air
conditioning compressors, refrigerating containers, building site
compressors and cranes.
