SS-EN Cast resin partitions for metal enclosed gas-filled high voltage switchgear and controlgear. Message to your colleague. A suffix may be added to either of these two types to further define the type of protection provided:.

A Corrigendum is available at, http: Shopping cart Close cart 0, foreach: What is a standard? Arc Resistant MV Switchgear Eaton’s VCP-W arc-resistant vacuum switchgear 5 kV through 38 kV class protects operating and maintenance personnel from dangerous arcing faults by redirecting or channeling the arc energy out the top of the switchgear.

If arcing occurs, the doors of the switchgear remain closed and the vents seal off-protecting the operator from contact with isee arc.
