It is supplied with all Ekip releases, mounted on a front connector dedicated and accessible to
the user, and can be replaced with release off and circuit breaker open.
IMPORTANT: the replacement of the Rating Plug with release on or circuit
breaker closed may cause malfunction of the release, or unwanted opening
of the switch.
NOTE: a trip unit can be equipped with any Rating Plug with a rated current of up to
Iu, i.e. the rated uninterrupted current of the circuit-breaker (indicate on the rating
plate of the circuit-breaker).
The release continuously checks for the presence of the Rating Plug, signalling its absence or
any errors in assembly or installation.
Once mounted, when the release is energized, its installation is requested.
On the Touch, Hi-Touch, G Touch and G Hi-Touch releases to activate the residual current
protection, it is necessary to mount a Rating Plug RC. They are also available Rating Plug L =
OFF, which allow you to cancel the protection L.

RC sensor RC is the external residual current sensor, which can be installed with Ekip Touch, Hi-Touch, G
Touch, and G Hi-Touch releases equipped with Rating Plug RC and Ekip Measuring Pro.
During programming of the release, its presence must be selected (see the menu Settings,
Circuit-breaker, Earth protection), that activates the RC residual current protection (see the
menu Advanced).
IMPORTANT: the RC toroid can be selected as an alternative to the Gext
toroid. Therefore the RC and Gext protections are alternatives.
