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)
