Phase failure relay, E3PF400VSY02

​The E3PF400VSY02 is a three-phase monitoring relay engineered to enhance the reliability and safety of electrical systems by overseeing phase sequence, phase failure, and asymmetry. Operating at a nominal voltage of 400/230V AC with a frequency range of 48 to 63 Hz, it ensures compatibility with standard three-phase networks. The relay features an adjustable asymmetry threshold between 5% and 25%, allowing customization to specific application requirements. It includes a fixed tripping delay of approximately 100 milliseconds to prevent nuisance tripping due to transient conditions. Equipped with two changeover contacts rated at 250V AC and 5A, the E3PF400VSY02 offers robust switching capabilities. Its compact 35mm DIN-rail mountable design facilitates efficient installation in control panels. LED indicators provide clear visual status updates: a green LED signals the presence of supply voltage, while a yellow LED indicates the relay output status. Engineered for precision and durability, the E3PF400VSY02 is an ideal solution for safeguarding motors and other critical equipment against phase-related faults in industrial and commercial settings. - Monitoring relays series ENYA - Phase sequence, phase failure monitoring - Asymmetry monitoring - Neutral conductor connection optional - Measuring voltage = supply voltage - Supply voltage 3x 400/230V AC - 2 changeover contacts - width 35mm - Installation type
