DC Short circuit switch
DC High current isolator

The vacuum contacts are integrated ina switching frame (steel or stainless steel).

This results in short circuit devices with sizes ranges from 6-400 kA with switching voltages ranging from 5 V DC - 30 V DC.

In atmospheres where there is exposure to harsh chemicals, the vacuum contacts are protected against external aggressive influences and ensure a long maintenance-free service lifespan.
