Aug 5 (Reuters) - Emerson Electric Co, a automation and power supply systems maker, reported a higher quarterly profit, helped by a rise in sales in North America.
Net earnings attributable to common shareholders rose to $728 million, or $1.03 per share, in the third quarter ended June 30, from $194 million, or 27 cents per share, a year earlier.
Revenue fell 0.5 percent to $6.31 billion.
Emerson said it now expects to hit the lower end of its 2014 revenue and profit forecast due to the ongoing economic uncertainty. (Reporting by Ankit Ajmera in Bangalore; Editing by Savio D'Souza)
