The Omron K8DT-AS1CA is the kind of current sensing relay you'd grab for monitoring motor loads across a lube route or conveyor line. It adjusts down to 2 mA and up to 500 mA, AC or DC, so it covers everything from a small solenoid to a modest motor draw. I've used these to catch a dry-running pump before it cooked the bearings—set the delay long enough to skip the start-up spike and you've got a reliable watchdog. It runs on straight 100-240 VAC, no separate power supply, and the SPDT contacts handle 5 A at 250 VAC, enough to sound an alarm or drop a starter.
