Arcing occurs due to increase in potential between the two contacts. Potential increases because of sudden opening of breaker leads to sudden reduction in current to zero. This means rate of change of flux is highest in inductive circuit and producing high potential between the contacts. Potential also increases due to release of conductance of cables.
