The 3UG3532-1AG20: The measuring voltage range of 15-600 V AC/DC covers most industrial control circuits from low-level DC signals up to 600 V line-to-line. The threshold and hysteresis adjustment allows tailoring the trip point and reset band to the specific application — useful for undervoltage or overvoltage monitoring on motor control feeders. The single-pole main current circuit (1 pole) and one CO contact limit the relay to monitoring duty; it is not intended for direct switching of high-current loads. The 22.5 mm width conserves rail space in dense layouts.
