FAQ
Where should this SPD be installed?
At the service entrance or main distribution board, as the first protection stage.
Does it support TT and TN systems?
Yes, with proper wiring modes L-N and N-PE.
What backup fuse is required?
Maximum 315 A gL/gG, as recommended in technical data.
Can it be replaced easily?
Yes, the cartridge is pluggable and field-replaceable.
Is remote monitoring available?
Yes, RC contacts are optional for status signaling.
What is the ISCCR rating?
50 kA short-circuit withstand capacity.
What happens if the module fails?
The thermal disconnector isolates it and the indicator turns red.
Welche Normen erfüllt sie?
