The arc-killer extinguishes an internal arc by directing it to a metal earthed short circuit. The arc is extinguished in less than 50 ms.
Mevoco's SV-25 Arc-Killer takes safety to a new level. Not just the operator and the environment are shielded from harm, but the super-swift arc extinguishing system allows cubicles to be back in operation very quickly in case of an internal fault. What's more, the arc-killer's improved security features place less strict demands on the installation room. As such, the Arc-Killer couples security and operational safety, with flexible room demands.
