Littelfuse 355400 is a versatile product suitable for both pilot duty and general purpose applications. With an output load rating of 470 VA @ 600 Volts for pilot duty and 10 A for general purpose, it provides reliable performance. It features torque termination for secure connections and supports wire sizes ranging from 12 to 18 AWG. The input AC line frequency can be set at 50 or 60 Hz, with the former increasing all delay timers by 20%. With a repeat accuracy of ±0.1%, this product offers precise control. The undervoltage trip voltage is set at 90%, and the trip delay range is adjustable from 2 to 30 seconds for under/over and unbalance voltage, with a fixed 2-second delay for single-phase faults. The maximum input power is 6 VA. The restart delay range can be set manually or adjusted from 2 to 300 seconds after a fault or power loss. The undervoltage reset voltage is 93%, and the voltage unbalance trip point can be adjusted from 2 to 8%. The overvoltage trip voltage is fixed at 110%, and the voltage unbalance reset is set at trip setting minus 1%. The trip point accuracy is ±1%, and the overvoltage reset voltage is 107%.
