The 1SVR730841R1200, part of the CM-S range, is a multifunctional three-phase monitoring relay designed to ensure supply quality and protect equipment. It monitors for phase sequence and phase loss, as well as over- and undervoltage conditions. Housed in a compact 22.5 mm wide enclosure, it features double-chamber cage connection terminals for secure wiring. This relay is crucial for protecting mobile three-phase equipment, motors, and installations from damage caused by supply voltage instability, phase reversal, or phase loss, and can be used for switching to emergency power supplies.
