V125 Arc Flash Protection Solutions

Critical infrastructure depends heavily on an uninterrupted supply of electric power. Arc flash protection devices help accomplish this and are used to improve safety and mitigate equipment damage. Schneider Electric is the pioneer in the field of arc flash protection with close to 50,000 arc flash systems and 600,000 sensors in service worldwide. The V125 arc flash protection module can detect an arc flash event in as little as 2 milliseconds and send a control command to an interrupting device. It can accommodate up to four (4) point sensors and has a wide range 24 to 240 volt ac or dc power supply. It can be DIN rail mounted or door mounted and is easily set via DIP switches.
