Economists had forecast output would increase 0.2%, Bloomberg News reported.
Utility output declined 1.8% following a 3.2% drop the prior month, Bloomberg said.
Manufacturing output, which makes up about three-quarters of the total, increased for the first time in three months on a gain in auto production.
