SPDs for LSA Technology
• Variable protection for 1 to 10 pairs in LSA systems
of 2/10 type
• 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

Lightning current arrester, surge arrester or combined lightning current
and surge arrester, pluggable into type 2 LSA disconnection blocks. The
integrated disconnection block contacts in the 10-pair plug-in SPD block
allow protected testing, disconnecting or patching within the system or
additional attachment of single-pair surge arresters.
DRL plug-in SPD block (10 pairs): Lightning current arrester for 10 pairs
DRL plug (1 pair):
Surge protective plug for 1 pair, energy-coordinated with DRL plug-in SPD blocks
Lightning current arrester, surge arrester or combined lightning current
and surge arrester 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 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.

The DEHNrapid LSA plug-in SPD block for LSA disconnection blocks effectively
protects sensitive hardware from overvoltage and at the same time
allows testing, disconnecting and patching of connected lines. The modular
arrester system for LSA disconnection blocks can be combined to a
combined lightning current and surge arrester and features fail-safe
overload protection with visual fault indication of the discharge elements.
