DEHNbloc, Lightning Current Arrester

$30.00$34.00

DEHNbloc lightning current arrester series offers single-pole and three-pole versions for lightning impulse currents up to 100 kA, depending on the system configuration. Modular single-pole versions are also available. Thanks to their high efficiency, coordinated spark-gap-based type 1 lightning current arresters are ideally suited for installation in the main distribution board of low-voltage consumer’s installations. The DEHNbloc series, from DEHN, is a critical component to  protect important assets from surge and lighting for manufacturers, industrial buildings, gas processing facilities, pipelines, and much more.

Description

DEHNbloc coordinated Type 1 lightning current arrester series offers single-pole and three-pole versions for lightning impulse currents up to 100 kA, depending on the system configuration. Modular single-pole versions are also available. They are suitable for use upstream of meter panels due to their high insulation resistance. The DEHNbloc series, from DEHN, is an important component for surge and lighting protection to protect critical assets for manufacturers, industrial buildings, gas processing facilities, pipelines, and much more.
