AC Current Detection Alarm Module - M3056 M3080 Style - 30A To 200A Range, Transformer Switch Sensor

This little black box is a really handy tool for monitoring if something electrical is on or off, or if it's drawing the right amount of power.

It's an AC current detection module, sometimes referred to as the M3056 or M3080 type.

You can set it up to detect currents from as low as 30 amps all the way up to 200 amps AC.

It works like a transformer, sensing the current flowing through a wire and then triggering an output.

You could use it to turn on a warning light if a pump stops, monitor motor loads, or for a hundred other DIY automation projects.

It's a simple switch induction relay, just wire it up and let it keep an eye on things for you.
