ENERGY REDUCTION MAINTENANCE SWITCHES WITH ACTIVATION ALERT

Abstract: an energy reducing maintenance switch (erms) connected to an electrical circuit includes: a switch that activates the erms upon being closed or turned-on; a normally-open first contact that closes to activate an instantaneous trip setting of a relay upon activation of the erms; and a second contact. the instantaneous trip controls an arc flash in the electrical circuit, and the activated instantaneous trip setting of the relay reduces time of the arc flash in the electrical circuit. upon activation of the erms, the second contact closes to initiate erms activation alert in two or more forms.
