The 3UG4622-1AA30: Supply voltage is 24 V DC nominal (20.4–26.4 V), with a contact rated 3 A at 250 V AC for switching alarm or control circuits.
The headline measuring range of 0.05 … 10 A is what you set via the digital interface; the relay can actually measure up to 15 A, giving headroom for brief overloads or a wider motor FLA without swapping the unit. Contact rating of 3 A at 250 V AC means it drives a contactor coil or a PLC input directly; at 24 V DC the same contact is rated 1 A. The auto-reset and external reset options let you choose between latching and automatic restart — handy for remote restart of a pump or conveyor.
Terminals accept 20–14 AWG solid or stranded, with 2× conductor capacity for looping through. Depth is 91 mm, height 92 mm — leaves room for wiring ducts in a standard 120 mm deep enclosure.
