The 1SVR730830R0300: This relay monitors single-phase AC/DC voltage levels, tripping or resetting based on user-set thresholds — a common choice for protecting motor starters, compressors, and pump controls from undervoltage or overvoltage conditions that can damage windings or cause nuisance trips.
Estimated lead time is 4 to 6 weeks, typical for an active ABB control product moving through distribution.
Integration Notes
No external power supply is needed — the relay is self-powered from the monitored voltage line. For panel builders: the relay occupies a single 22.5 mm module width, leaving adjacent DIN slots free for contactors, breakers, or other monitoring relays in the same row.
