The 3UG4641-1CS20: A built-in LCD display shows the measured parameters and configuration menus, making setup straightforward without external tools. The start-up delay is adjustable from 0 to 99 seconds, and an external reset input allows remote acknowledgment of trip conditions.
The measurable current range of 0.2 to 10 A covers most motor and feeder circuits in industrial panels. The relay's output contacts are rated at 3 A at 250 V and 400 V (50/60 Hz), which is sufficient to drive a contactor coil or PLC input directly. For DC switching, the contacts handle 1 A at 24 V, 0.2 A at 125 V, and 0.1 A at 250 V — enough for pilot-duty signaling but not for heavy DC loads. The storage and transport temperature range of -40 to +85 °C ensures the part survives shipping and storage extremes.
