An electrical components factory in Newtown is closing this year.  The Hubbell plant, which employs 140 people, is the largest of the Shelton-based company's facilities in Connecticut.  The closure will happen over the next six months and most of the work will move to Puerto Rico. 

Hubbell earlier announced the Bethel closure as part of an ongoing operational efficiency initiative.  The plant in Bethel employs 54.  That work is moving to Alabama.   Hubbell will continue to employ more than 650 employees in Connecticut. 

Harvey Hubbell, a pioneer in electrical components including the light socket, founded the company in 1888.  It's not related to the Hubble Telescope, which was built in Connecticut by Perkin-Elmer at a plant now owned by Collins Aerospace, part of UTC.
