Simple Mini current sensor for amperage (NO) contacts

I am looking for a mini current amp sensor to install in control panels that are too challenging to mount anything very large to the back plate. This will be a simple device (NO) that will sense AC current (pump starting) inline through an IEC starter overload combination. Nothing too big and we have around 200 of these panels to retro with a current sensor. Any idea of what would be available to just do the simple task at hand?

Hello eddie1 and welcome to the DigiKey TechForum.

Would you be looking for something like the options linked HERE? It appears they have more information as well as installation instructions listed on the manufacturers page.
