What Is An Arc Chute The cold cathode arc chute is well suited to the interruption of dc currents as it provides a fairly fixed or predictable arc voltage regardless of the arc current. Arc chutes can be found inside circuit breakers contactors isolators and other high current interruption devices. A suitable energy dissipater or outlet structure is required at the base of the chute. The design is such that there are no electrical parts that could break or fail Dynamic Flap System Ventilation system.
