Abstract (en)
[origin: WO9519631A1] A double break circuit breaker includes a pair of contact assemblies, an arc stack and an arc extractor. At least one of the contact assemblies interrupts the current by moving from a normally closed position to at least one open position, and the arc stack is disposed sufficiently adjacent the pair of contact assemblies to absorb arc energy resulting from one of the primary contact assemblies moving from the normally closed position. The arc extractor has a conductive portion located adjacent the arc stack and sufficiently adjacent the pair of contact assemblies to prevent the arc energy within the arc stack from collapsing into a region between the pair of contact assemblies.
