Feb 4 (Reuters) - Electrical equipment maker Hubbell

beat estimates for fourth-quarter profit on Tuesday,

helped by strong demand in its utility segment for devices used

in power grids.

Hubbell, which manufactures and sells electrical and utility

solutions, has benefitted from ongoing upgrades to the U.S.

power grid system.

Sales in the company's utilities solutions unit rose 4.4% to

$847.1 million.

The Shelton, Connecticut-based company reported an adjusted

profit of $4.10 per share for the quarter ended Dec. 31,

compared with analysts' average estimates of $4.02 per share,

according to data compiled by LSEG.

Its revenue fell about 1% year-on-year to $1.33 billion,

compared with an estimate of $1.41 billion, due to weakness in

grid automation and electrical business.
