MX160A, MX180A & MX200A are single or 3-phase monitoring relays. The relays are designed for application where it required to maintain the voltage within set limits. A built-in adjustable time delay prevents nuisance tripping. • Electronic monitoring relay • Voltage monitoring for single 3-phase system • Phase failure monitoring • Adjustable voltage limit • Adjustable delay time • Indicators for voltage fault • Indicators for power and output ON • ANSI Code : 27, 47, 59
