The back-up module allows to realize savings on your installations by reducing the power of cut of your circuit breakers. The filiation allows to use the limitation power of the circuit breakers, in such a way to install afterwards the reduced breaking capacity circuit breakers, in order to decrease the cost of the installation.

The association of two circuit breakers in back-up is predicted by the building norms of devices and installation.

This module allows thus the realisation of savings regarding the choice of circuit breakers and the management of the installation.
