Abstract
The contacts and nozzle of a fluid blast circuit breaker are constructed to have a cross section with a shape other than circular or square. Such cross section facilitates providing the fluid for extinguishing an arc in a circuit breaker at a velocity perpendicular to the arc greater than the fluid velocity in a circular or square configuration nozzle having the same cross sectional area. Such high velocity fluid flow facilitates interrupting the arc by increasing the cooling rate of fluid flow past the arc.
