Power-Zone 4 Arc Resistant | Schneider Electric

A suffix may be added to either of these two types to further define the type of protection provided:. Please note that the selected standard is invalid. Ampgard AR Motor Control Center MCC Iese unique isolation switch design disconnects the starter from the medium voltage source in the rear arc chamber, not in the front starter compartment—improving protection for workers in the event of an arc flash. Electrical Communications Vehicle Communications Follow: 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.
