Sign up for newsletters. 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.

Ampgard AR Motor Control Center MCC The unique isolation switch design disconnects the starter from c3.720.7 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.

Arc Resistant Low Voltage Switchgear This enclosure was designed to be robust enough to contain the high c37.207 and heat present during an arc flash event. 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.

When you use our service you can be assured the latest editions and easy access. Special designation that supplements the Type 1 designation, but identifies additional v37.20.7 resistance in certain structures Eaton offers arc resistant medium voltage MV ,and low voltage LV switchgear and arc resistant MV motor control.
