Hyper Immunized differential protection for protection during charging of electric vehicles.
Recommended for protecting charging stations with DC leak detection.
Description
HI type differential switches are suitable for electrical equipment that contains devices capable of producing fault currents with a direct component.
HI (Hyper Immunized): These are devices that have ''reinforced immunity'', reducing untimely shooting situations, protecting equipment that generates disturbances (micro computer, electronic ballasts,...)

The first impression was that the box appeared well built and rugged enough to do the job. The only tricky bit was getting the plug to go fully into the box. I turned the box over with the plug on a table and pushed the box onto the plug with a reassuring click. Charged the car with no problems. A bit pricey... but does the job.
