What this relay does
The 1SVR730841R0200: This relay monitors current on a single-phase or three-phase line and trips when the current deviates outside a set window — overcurrent, undercurrent, or phase imbalance. It sits in the same CM-SRS family as the 11P variant; the 'S' suffix typically indicates a specific adjustment range or output configuration, but the core function is current-level supervision for motor and load protection.
