Littelfuse 455480R is a pilot duty relay with an output load rating of 470 VA at 600 Volts. It has a torque termination type of 7 in-lbs and supports wire sizes of 12 - 18 AWG. The input AC line frequency can be set at either 50 or 60 Hz, with a 20% increase in delay timers for 50 Hz. It offers precise repeat accuracy of ±0.1%. The undervoltage trip voltage is set at 90%, with a trip delay range of 2 - 30 s for under/over and unbalance voltage. For single-phase faults, a 2 s trip delay is applied for faults exceeding 25% of the unbalance voltage. The maximum input power is 6 VA. It provides a restart delay range of 2 - 300 s, with a manual adjustment option. The undervoltage reset voltage is 93%, and the voltage unbalance trip point can be adjusted from 2 to 8%. The overvoltage trip voltage is set at 110%, with a voltage unbalance reset of trip setting minus 1%. The trip point accuracy is ±1%, and the overvoltage reset voltage is 107%.
