CM-PVS.41S phase and voltage loss monitoring
The ABB 1SVR730794R3300 is a CM-PVS.41S phase and voltage loss relay, classified under General Purpose Relays with a subcategory of Phase & Voltage Loss Relays. This relay monitors three-phase mains for phase loss, phase sequence, and undervoltage conditions, tripping the output when the supply deviates outside set thresholds.
