Features:

The Alpha resistor components consist of fully welded wirewound resistors, mounted in silica sand, insulated with MICANITE and mounted in an anodised aluminium house. The base material is high temperature MICANITE which is long time stable at 700°C and short time resistant up to 1000°C. The construction has high resistance to temperature changes.

The resistors comply with IP50 giving electrical and thermal protection.
