HOBUT – M200‑V34U – 3‑Phase 4‑Wire Under‑Voltage Relay, Self‑Powered, DIN‑Rail

The HOBUT M200‑V34U is a DIN-rail mounted under-voltage protection relay for 3-phase 4-wire systems. It monitors phase-to-neutral voltage and trips if it drops below the set threshold. Self-powered and compact, it’s ideal for automation panels, motor protection, and power quality monitoring in industrial and commercial environments.
