What is a standard? Arc Resistant MV Fused Load-Interrupter Switchgear Standard safety features include through the door switching, visible blade viewing windows, door interlocks and full type 2B arc resistant rating even with control doors open. A method of identifying the capabilities of this equipment is given.

Arc Resistant Switchgear

General terms and conditions Cookies och Javascript Disclaimer Contact. Arc resistance is maintained even while opening designated low voltage compartments C: 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.

Service conditions, installation, and application of equipment are also discussed. Special designation that supplements the Type 1 designation, but identifies additional arc resistance in certain ieer Eaton offers arc resistant medium voltage MV ,and low voltage LV switchgear and arc resistant MV motor control. 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.
