Surge protective devices type 1
This type of surge protective devices are recommended on electrical installations where the buildings are fitted with lightning conductor. The minimum value of shock current (I imp) = 12.5 kA.
Application
Other technical characteristics
- With a discharge current wave 10/350 µs (I imp) which is similar to lightning current on direct strike, those SPD's must have the capacity to divert out this energizing wave.
- Monobloc SPD's type 1 have an LED for function indication for each phase on the front
- Connection capcaity: 35mm² flexible conductor, 50mm² rigid conductor
