Type-A RCD failing 180 degree ramp test

Former Community Member

Hi


We are testing a type-A RCD (see image: "ABB") with a METREL MI 3152 (see image: "MI 3152 test").

As the image shows, the ramp test (I delta) is failing to trip the RCD for the negative half wave.


Have oneone seen this before?

    My wife has just tried the spot the difference competition and agrees the moulded cases look near enough identical, but agrees the label on the top RCD has the appearance of less than perfect scan and print when compared with the lower RCD.
