Minhe 3 x 380V FKV-24F Phase Relay for Overvoltage, Undervoltage and Phase Asymmetry DIN Rail Mount Industrial Control
Minhe 3 x 380V FKV-24F Phase Relay for Overvoltage, Undervoltage and Phase Asymmetry DIN Rail Mount Industrial Control
Voltage Monitoring & Protection This phase relay continuously checks 3 x 380V AC supplies against overvoltage (U>), undervoltage (U<) and phase asymmetry. It protects industrial engines and equipment from harmful power fluctuations and phase loss and cuts off the load when faults are detected.
Phase Querying and Asymmetry Control: The device checks the correct phase sequence and monitors phase balance. If the asymmetry ratio exceeds the set value or the phase order is incorrect, it triggers a response to prevent equipment damage caused by phase reversal or unbalanced loads.
RELAY OUTPUT & STATE DISPLAY: Features clear LED indicators for overvoltage (U>), undervoltage (U<), asymmetry (asym) and phase error. The internal relay switches outputs (5A/250V) based on fault conditions, with an integrated start delay (3-4 sec.) and trigger delays (2 seconds) to avoid annoying triggers.
INDUSTRIAL DIN RAIL DESIGN: Housed in ABS housing for standard DIN rail mounting, control panels. With a wide operating temperature range (-20°C to +55°C) and low power consumption (<4VA), it is designed for continuous industrial use.
EASY CONNECTION & COMPACT SIZE Connects via a terminal block that accepts up to 1.5mm² of wires. Its compact size saves space in control cabinets, and the clear wiring diagram on the case simplifies installation for electricians and maintenance teams.
