VacClad-W arc-resistant switchgear is a metal-clad, medium-voltage switchgear designed to safely contain and redirect the thermal energy and blast from an arc fault, should one occur, regardless of the originating location of the arc. The 5–15 kV VacClad-W arc-resistant switchgear has a type 2B rating with an arc-flash boundary of zero, offering enhanced safety even when the control compartment door is open.
