Phase failure relay E1PF480Y/277VSY01

​The E1PF480Y277VSY10 is a phase monitoring relay designed to ensure the stability and reliability of three-phase systems. Operating at a nominal voltage of 480V with a star point at 277V, it continuously monitors phase sequence, phase failure, and undervoltage conditions. The relay is equipped with an adjustable undervoltage threshold ranging from 75% to 95% of the nominal voltage, allowing for customized protection settings. Its compact design facilitates DIN-rail mounting, optimizing space within control panels. Clear LED indicators provide real-time status updates, displaying operational states and alerting to any detected faults. Engineered for durability and precision, the E1PF480Y277VSY10 is an ideal solution for safeguarding motors and other critical equipment in industrial settings. - Monitoring relays series ENYA - Voltage monitoring in 3-phase networks - Phase sequence, phase failure monitoring - Asymmetry monitoring - Supply voltage = measuring voltage - Supply voltage 208V - 480V AC - 1 changeover contact - width 17.5mm - Installation type
