AC Over Under Voltage Relay 80A 3P+N Bottom 3 phase
AC Over Under Voltage Relay 80A 3P+N Bottom 3 phase
The AC Over/Under Voltage Relay 80A 3P+N Bottom 3-Phase is a robust protective device designed to safeguard three-phase electrical systems against voltage fluctuations. By continuously monitoring incoming voltage levels, this relay ensures that connected equipment operates within safe voltage limits, preventing damage caused by overvoltage or undervoltage conditions.
Rated at 80 Amps, this relay is ideal for industrial, commercial, and large residential installations. The 3P+N design protects all three phases and the neutral line, providing comprehensive coverage for three-phase circuits. Its bottom-mounted terminals simplify installation in distribution panels, ensuring secure connections while minimizing space requirements.
The relay automatically disconnects the load when voltage exceeds or drops below preset thresholds, reconnecting it once the voltage stabilizes. This feature is essential for protecting motors, compressors, pumps, and other sensitive three-phase equipment from damage, improving system reliability, and extending the lifespan of connected devices.
Engineered for precision, durability, and safety, the AC Over/Under Voltage Relay 80A 3P+N Bottom 3-Phase provides reliable voltage protection and ensures uninterrupted, safe operation of three-phase electrical systems.
