To connect measuring devices to RCD, RCCB, GFCI, circuit breakers, etc.
without loosening their screws (the screws must be made of iron or steel).
For the production of secure semi-permanent (several hours) connections between 4 mm banana plugs and the iron or steel screws of RCD-, RCCB-, GFCI-, circuit breaker terminals etc.
, without loosening them.
The magnetic tip allows this adapter to "stick" to the screws or other electrical contacts that are made of steel or iron or nickel (ferromagnetic materials) to a large extent.
Typically attached to the screws of some circuit breakers, residual current circuit breakers.
The magnetic strength depends on the shape and material of the contact.
The magnetic strength is lower for a steel screw with lens head than for a steel screw with flat head.
Therefore, it is important that the contact is at the bottom of a cavity with an internal diameter equal to or greater than 6.
7 mm but close to 6.
7 mm.
