Littelfuse PLM6405 is an 8-pin plug-in relay with a maximum output load rating of 10 A resistive @ 240 Volts. It has a power consumption of ≤2 W and a reset time of Automatic. This relay provides surge protection according to IEEE C62.41-1991 Level B standards and has a response time of ≤200 ms for phase loss and phase reversal. This voltage detection relay is designed for 3-phase delta or WYE input with no connection to neutral. The trip delay range is fixed at 5 s and the undervoltage trip voltage is adjustable between 88% to 92% of the adjusted line voltage. The undervoltage reset voltage is +3% of the trip voltage. The voltage unbalance trip point is fixed at 4% and the voltage unbalance reset is -0.7% unbalance typical. The input phase sequence is A, B, C. The input voltage maximum is 270 V.
