Yes they do, though their trip time for "unbalanced phases" is much faster than that of the conventional thermal magnetic overloads, such as GV2/3 series or LRD series.
The GV7 and LR9F series will both trip after 4 seconds (+ or - 20%) on phase loss where an LRD or GV2/3 can keep running for up to 2 hours unless an overload is detected in the remaining phases.
