Choosing an integrated disconnector

In compliance with the NF EN 61643-11 standard, the FUSADEE® SPDs must be installed along with a disconnector. Several configurations are available:

• In series to guarantee a continuity of service

• In series in the power line to guarantee a continuity of protection. In such case, the choice of the integrated disconnector must be made with regards to the earthing system.

Here are the different possibilities:

• A ground fault interruptor (for TT or TN earthing systems)

• A magneto-thermal circuit breaker (for IT earthing systems)

• Fuses
