SEW

The SEW ST-850 is a reliable phase sequence meter for checking phase rotation and detecting open phases in three-phase power systems, operating at 90-600V AC, 50/60Hz, featuring three color-coded leads (R, S, T) with crocodile clips for secure connections, large neon indicators for clear phase presence visualization, and sturdy industrial construction (134×85×45mm, 510g) for demanding field environments. This professional 3-phase rotation tester enables electricians and maintenance technicians to verify correct phase sequence (clockwise vs counterclockwise) before connecting motors, pumps, compressors, and conveyors, detect missing or open phases in power supplies, prevent reverse rotation damage, ensure proper generator synchronization, commission new electrical equipment correctly, and troubleshoot phase-related issues in industrial power systems.
