Surge arrester type 1 for low voltage power lines
CM 400
Indelec
They are made up of :
- a primary protection stage using DGA 70 kA overvoltage arresters
- a secondary protection stage using DGX 10 kA overvoltage arresters
- an inductive co-ordination resistor designed to uncouple the two protection stages
- an overvoltage arrester protection breaker
The pre-wired sub-assembly is set in a lockable metal cabinet. An LED display on the cabinet door shows the voltage and operational status of each overvoltage arrester.
