Siemens 5TT3 Series
Siemens 5TT3 series phase monitors monitor the voltages in three-phase system and signal the power failure of one or more phases over a floating contact. Phase sequence monitors monitor the phase sequence in three-phase systems and signal any changes in the phase sequence - change of rotating field - over a floating changeover contact.
