We also use them to simply detect low voltages that are not a lost-phase. Occasionally there is sensitive equipment to protect in this way.

Is there a standby generator or another source of power on the system? The relay might be signaling for transfer to another source or be part of an interlocking scheme to prevent backfeeding.
Many possible uses.

As for DRWeigh's statement "to prevent 3-phase motors from running single-phase, or attempting to start single-phase"
From the control schematic, it only shows the source from 110 DC supply and there is motor integrated together. Does this mean it is single-phase motor of MCCB and there's 3 items for each control schematic design on each phases.
