Phase failure relay, K3YM400VSY20

​The K3YM400VSY20 is a versatile voltage monitoring relay suitable for both single-phase and three-phase systems operating at 400V AC. It offers multiple monitoring functions, including overvoltage, undervoltage, phase sequence, phase failure, and asymmetry detection, providing comprehensive protection for electrical installations. The relay features adjustable thresholds and time delays, allowing customization to specific application requirements. Equipped with two changeover contacts rated at 250V AC and 5A, the K3YM400VSY20 ensures reliable switching performance. Its compact 38mm plug-in housing is designed for 11-pin socket mounting, facilitating straightforward integration into control panels. LED indicators provide clear visual feedback: a green LED indicates the presence of supply voltage, a red LED signals fault conditions based on set parameters, and a yellow LED shows the status of the output relay. Engineered for precision and durability, the K3YM400VSY20 is an ideal solution for safeguarding sensitive equipment from voltage irregularities in various industrial and commercial applications. - Monitoring relays - KAPPA series - DC voltage monitoring in 1-phase networks - Multifunction - supply voltage = measuring voltage - 2 changeover contacts - Pluggable - Construction width 38mm - cap dimension 45mm
