Arc Resistant Switchgear Understanding arc behaviour and developing and testing internal arc-resistant switchgear, has enabled manufacturers to create robust systems. Mechanisms are designed where an “arc burning place” is created successfully at the very moment of arcing, triggered by the arc pressure itself via a hinge construction.

Arc-resistant Magnum DS low-voltage switchgear (ArcGard)
Arc-resistant low-voltage switchgear protects operating and maintenance personnel from dangerous arcing faults by channeling the arc energy out the top of the switchgear. Arc faults, caused by human error or insulation failure, can generate thermal energy as high as 35,000 °F and a blast equivalent to 20.7 lb of TNT.
Switchgear designed and tested to mechanically withstand the electric arc. Protection is afforded by the containment of the arc within the switchgear and the means to direct the arc gases and debris to a safe area. Passive solutions also include advanced switchgear design features to reduce the probability of an arc flash occurring.
