Littelfuse PLM6805 is a high-quality voltage monitoring relay designed for 3-phase delta or WYE input types with no connection to neutral. It has a load rating of 10A resistive at 240V, with surge protection according to IEEE C62.41-1991 Level B. It features an octal 8-pin plug-in termination type rated at 600V, automatic reset time, and a trip delay range of 5s fixed. The relay offers undervoltage trip voltage of 88-92% of adjusted line voltage, voltage unbalance trip point of 8% fixed, and phase loss detection of ≥35%.
