SS Protective screens of insulating material for indoor switchgear with rated voltage above 1 kV and up to and including 36 kV – Design, use and testing. Arc Resistant MV Switchgear Eaton’s VCP-W arc-resistant vacuum switchgear 5 kV through 38 kV class protects operating and maintenance iee from dangerous arcing faults by redirecting or channeling the arc energy out the top of the switchgear.

Arc Resistant Low Voltage Switchgear This enclosure was designed to be robust enough to contain the high pressure and heat present during an arc flash event. Report error on page. FlashGard Motor Control Center This MCC lowers the probability of the creation of a short circuit phase-to-phase or phase-to-ground fault, lowering the possibility of an arc flash event.
