DEHNguard S/M ACI 275 Type 2 arrester -Surge protection devices
For the protection of low voltage equipment against transient voltage and current surges mainly from atmospheric origin (lightning) and transient produced by switching characteristics such as in switching of distribution networks, transformers, motors, etc.
Minimum requirement as per SANS 10142-1:2008 anex L for use in all electrical distribution boards and sub boards. For installation in conformity with the lightning protection zone.
With its new integrated switch/spark gap combination, ACI (Advanced Circuit Interruption) technology reduces complexity, improves system availability and saves time, space and material costs.
