		<description><![CDATA[Depending upon the direction of air blast in relation to the arc;air blast circuit breakers are classified into: (i)Axial-blast type in which air-blast is directed along the arc path as shown in figure below. (ii) Cross-blast type in which air blast is directed at right angles to the arc path as shown in figure below [...]]]></description>

		<description><![CDATA[These type of breakers employ &#8216;air blast&#8217; as the quenching medium.The contacts are opened by air blast produced by the opening of blast valve.The air blast cools the arc and sweeps away the arcing products to the atmosphere.This rapidly increases the dielectric strength of the medium between contacts and prevents from re-establishing the arc.Consequently the [...]]]></description>
