PVariable protection for 1 to 10 pairs in LSA systems of the 2/10 series LSA disconnection block function integrated in the lightning current arrester provides protection during testing, disconnecting and patching Modular system of lightning current and surge arresters can be combined to a single combined arrester
The DEHNrapid LSA arrester series is a modular system of lightning current arresters, surge arresters or combined lightning current and surge arresters that can be plugged into type 2 LSA disconnection blocks. The lightning current carrying 10-pair plug-in SPD block incorporates gas discharge tubes (optionally available with visual fault indication) and disconnection block contacts. This allows testing, disconnecting or patching of pairs with plugged-in protection or the additional attachment of single-pair surge arresters to ensure optimal protection of terminal equipment. The surge arresters snap into the earthing frame and can be removed as a block, whenever required.
Lightning current carrying SPD block with gas discharge tubes optionally available with visual fault indication and fail-safe feature.
Pluggable surge arresters in the form of protection blocks can be plugged into terminal or disconnection blocks.
Application-specific protection modules for protecting terminal equipment.
Modular design consisting of a plug-in SPD block with gas discharge tubes, earthing frame and application-specific protection modules.
